AbstractThe evolution of the fireball resulting from the August 2020 Beirut explosion is traced using amateur videos taken during the first 400 ms after the detonation. Thirty-nine frames separated by 16.66–33.33 ms are extracted from six different videos located precisely on the map. Time evolution of the shock wave radius is traced by the fireball at consecutive time moments until about $$ t \approx 170$$ t ≈ 170 ms and a distance $$ d \approx 128$$ d ≈ 128 m. Pixel scales for the videos are calibrated by de-projecting the existing grain silos building, for which accurate as-built drawings are available, using the length, the width, and the height and by defining the line-of-sight incident angles. In the distance range $$ d \approx $$ d ≈ 60–128 m from the explosion center, the evolution of the fireball follows the Sedov–Taylor model with spherical geometry and an almost instantaneous energy release. This model is used to derive the energy available to drive the shock front at early times. Additionally, a drag model is fitted to the fireball evolution until its stopping at a time $$ t \approx 500$$ t ≈ 500 ms at a distance $$d \approx 145\pm 5$$ d ≈ 145 ± 5 m. Using the derived TNT equivalent yield, the scaled stopping distance reached by the fireball and the shock wave-fireball detachment epoch within which the fireball is used to measure the shock wave are in excellent agreement with other experimental data. A total TNT equivalence of $$ 200\pm 80\,\mathrm{t}$$ 200 ± 80 t at a distance $$ d \approx 130$$ d ≈ 130 m is found. Finally, the dimensions of the crater size taken from a hydrographic survey conducted 6 days after the explosion are scaled with the known correlation equations yielding a close range of results. A recent published article by Dewey (Shock Waves 31:95–99, 2021) shows that the Beirut explosion TNT equivalence is an increasing function of distance. The results of the current paper are quantitatively in excellent agreement with this finding. These results present an argument that the actual mass of ammonium nitrate that contributed to the detonation is much less than the quantity that was officially claimed available.

In this paper, blast effect of oil-associated gas in gas injection wells is determined when using air injection displacement, and on this basis, the relevant safety distance is determined also. Numerical simulation is used to calculate the overpressure distribution, explosion energy and TNT equivalence of combustible gas explosion in gas injection wells. Based on shock wave damage criterion, the safety distances in seven levels are obtained, which are personnel minor injuries, severe injuries, death, and destruction of buildings with mild, moderate, severe manage and destroying. Therefore, technical support is provided to accident prevention, emergency and rescue.

This paper details the development of an engineering assessment procedure for reinforced concrete (RC) column failure when subjected to time-variant coupled axial and lateral loads due to internal building detonations. This is based on a comprehensive parametric study conducted using an advanced uncoupled Euler–Lagrange numerical modeling; splitting the structural and flow solvers for maximum integrity and accuracy. The column assessment charts discussed in this paper provide threshold combinations of TNT equivalence and stand-off distance for a range of column residual axial capacity levels corresponding to two key internal blast environments: Vented and contained. This will be of direct relevance to both practitioners and researchers involved with protective design of civilian and military buildings.

This paper conducts a parametric analysis on the response of geopolymer-based ultra-high-performance concrete (G-UHPC) slabs reinforced with steel wire mesh (SWM) subjected to contact explosions using the validated Continuous Surface Cap (CSC) model. Firstly, based on the available experimental data, the CSC model parameters, which account for the yield surface, damage formulation, kinematic hardening, and strain rate effect, were comprehensively developed for G-UHPC. The modified CSC model was initially assessed by comparing the quasi-static test results of G-UHPC. Then, the numerical modeling was performed on 200 mm thick SWM-reinforced G-UHPC slabs against 0.4 kg and 1.0 kg TNT contact explosions. The fair agreement between the numerical and experimental data concerning the local damage of the slabs was reported to demonstrate the applicability of the material and structural models. With the validated numerical models, a parametric study was further acted upon to explore the contribution of the variables of SWM, slab thickness, and TNT equivalence on the local damage and energy evolution of G-UHPC slabs subjected to contact blasts. Moreover, based on simulation results from the parametric study, an updated empirical model was derived to evaluate the local damage pattern and internal energy absorption rate of SWM-reinforced G-UHPC slabs.

Quine's “New Foundations” (NF) was first presented in Quine [10] and later on in Quine [11]. Ernst Specker [15, 13], building upon a previous result of Ehrenfeucht and Mostowski [5], showed that NF is consistent if and only if there is a model of the Theory of Negative (and positive) Types (TNT) with full extensionality that admits of a “shifting automorphism,” but the existence of such a model remains an open problem.In his [8], Ronald Jensen gave a partial solution to the problem of the consistency of Quine's NF. Jensen considered a version of NF—referred to as NFU—in which the axiom of extensionality is weakened to allow for Urelemente or “atoms.” He showed, modifying Specker's theorem, that the existence of a model of TNT with atoms admitting of a “shifting automorphism” implies the consistency of NFU, proceeding then to exhibit such a model.This paper presents a reduction of the consistency problem for NF to the existence of a model of TNT with atoms containing certain “large” (unstratified) sets and admitting a shifting automorphism. In particular we show that such a model can be “collapsed” to a model of pure TNT in such a way as to preserve the shifting automorphism. By the above-mentioned result of Specker's, this implies the consistency of NF.Let us take the time to explain the main ideas behind the construction. Suppose we have a certain universe U of sets, built up from certain individuals or “atoms.” In such a universe we have only a weak version of the axiom of extensionality: two objects are the same if and only if they are both sets having the same members. We would like to obtain a universe U′ that is as close to U as possible, but in which there are no atoms (i.e., the only memberless object is the empty set). One way of doing this is to assign to each atom ξ, a set a (perhaps the empty set), inductively identifying sets that have members that we are already committed to considering “the same.” In doing this we obtain an equivalence relation ≃ over U that interacts nicely with the membership relation (provided we have accounted for multiplicity of members, i.e., we have allowed sets to contain “multiple copies” of the same object). Then we can take U′ = U/≃, the quotient of U with respect to ≃. It is then possible to define a “membership” relation over U′ in such a way as to have full extensionality. Relations such as ≃ are referred to as “contractions” by Hinnion and “bisimulations” by Aczel.

Abstract Due to differences in charging technology, test methods, etc. the same explosive can obtain different explosive parameters in different tests. The difference in performance of explosives with different parameters is the focus of engineer’s design. This paper uses the TNT equivalence (TNTe) to compare the parameters of three CL-20 based explosives reported in the previous literature. In this paper, TNTe is attained from Peak overpressure (OP) and impulse (IM), calculated by AUTODYN software and is compared with the TNTe calculated by Cooper Method, Hydrodynamic Work, heat of detonation method. The results show that the difference of TNTe among different parameters can reach 30%. The TNTe calculated by heat of detonation method is too low to be recommended. The average value of TNTe calculated by other methods is 1.69±0.09. More accurate TNTe needs to be used with caution, including data sources and limitations.

Thirteen hours after the tragic explosion of the U.S. space shuttle “Challenger” at an altitude of 15km on 29th January 1986, a sequence of strong infrasonic waves was received by a set of sensitive microbarographs on the ground level about 14300km distant. These waves, with periods 400–700 seconds, amplitude about 30Pa and propagation velocity about 300m/s are very similar in character to those from nuclear explosions. Based on the analysis of the power spectrum, the main period of the signal can be determined as 537 sec and over 90 per cent of the energy concentrates within the range of 300–1000 sec. According to the theoretical formula for nuclear explosions, the equivalence of this explosion can be estimated from the wave characters as 140 Mt of TNT. This estimation is on the high side, owing to the fact that, compared with nuclear explosions, the altitude at which the explosion has taken place is much higher and the mechanisms of these two explosions are quite different.

In the semiconductor industry, hydrogen is used with many other hazardous and dangerous substances with flammable, toxic, and corrosive properties. In order to safely handle them, convenient-to-use gas cabinets are often required. As known well, hydrogen is highly flammable and explosive, and risk analysis needs to safely use the gas in the cabinets. In this study, overpressure and impact according to various gas cabinet conditions were measured when hydrogen leaks in the gas cabinet, and the effect of overpressure on the protective wall was simulated. For the research, a demonstration experiment was conducted by custom manufacturing a gas cylinder cabinet identical to the standard used in the field, and the protection performance analysis was performed by reverse-engineering it through 3D scanning. As a result of the demonstration experiment, the maximum pressure at the time of hydrogen gas explosion in the gas cylinder cabinet was measured at 0.3 bar. After calculating the detonation pressure propagation profile using the TNT equivalence method, the protective performance of the protective wall was confirmed using AUTODYN. The maximum stress of the concrete and the maximum stress of the reinforcing bar due to the explosion in the gas cylinder cabinet were calculated to be 30.211 MPa and 112.88 MPa, respectively, which do not exceed the tensile strength of concrete and the yield strength of the reinforcing bar. This result is expected to be of great help to the development of the semiconductor industry by suggesting the rationale for mitigating the firewall when changing the semiconductor layout.

Lately, explosions with a large TNT equivalent have occurred with alarming frequency causing severe structural damage. The damage suffered by these structures has been exacerbated by the ground shock generated during these large equivalent explosions. The aim of this work is to study the ground-shock propagation behaviors, the areas affected by them, and determine the minimum safe distance for various structures. To measure ground shock data at different distances from the epicenter of the blast, actual 1 t and 10 t TNT surface explosion experiments were performed. The velocity and attenuation coefficient of the ground shock generated by the 1 t TNT surface explosion were determined, and the empirical equations provided by the UFC 3-340-01 standard were validated. Additionally, numerical analyses were performed to analyze the effects of ground shocks on buildings around an explosion. The maximum particle vibration velocities and attenuation behaviors of a 10 t TNT surface explosion as well as the minimum safe distances for a variety of structures were obtained from the numerical analyses.

Hydrogen gas storage place has been increasing daily because of its consumption. Hydrogen gas is a dream fuel of the future with many social, economic and environmental benefits to its credit. However, many hydrogen storage tanks exploded accidentally and significantly lost the economy, infrastructure, and living beings. In this study, a protection wall under a worst-case scenario explosion of a hydrogen gas tank was analyzed with commercial software LS-DYNA. TNT equivalent method was used to calculate the weight of TNT for Hydrogen. Reinforced concrete and composite protection wall under TNT explosion was analyzed with a different distance of TNT. The initial dimension of the reinforced concrete protection wall was taken from the Korea gas safety code book (KGS FP217) and studied the various condition. H-beam was used to make the composite protection wall. Arbitrary-Lagrangian-Eulerian (ALE) simulation from LS-DYNA and ConWep pressure had a good agreement. Used of the composite structure had a minimum displacement than a normal reinforced concrete protection wall. During the worst-case scenario explosion of a hydrogen gas 300 kg storage tank, the minimum distance between the hydrogen gas tank storage and protection wall should be 3.6 m.

Translation is a complex construct comprising both process (translating) and product (equivalent). The translation process is characterized as a double negotiation, consisting of two phases: 1. interpretation of a source text’s pragmatic meaning and 2. rendering this into a target text in line with target-language expectancy norms. As an intertextual negotiator, the translator should be highly sensitive to both sourcelanguage and target-language conversational and conventional implicatures. The operation of both types of implicatures is illustrated through examples from Arabic/English translation praxis. Finally, a distinction is made between the descriptive and evaluative senses of equivalence, the latter being seen as synonymous with fidelity, which is defined in translation in terms of pragmatic success or failure (infidelity). Résumé La traduction et l’équivalence sont définies en tant que signification pragmatique (intention) du texte-auteur. La traduction est une construction mentale complexe qui englobe à la fois l’acte de traduire et le produit (équivalent). Le processus de traduction se caractérise par une double négociation comportant deux phases: 1) l’interprétation de la signification pragmatique d’un texte-source et 2) sa traduction dans un texte-cible qui respecte les normes escomptées dans la langue-cible. Le traducteur, négociateur intertextuel, doit être extrêmement sensible aux significations implicites en matière de conversation et de convention de la langue-source et de la langue-cible. Le fonctionnement des deux types de significations implicites est illustré par des exemples tirés de la pratique de la traduction arabe-anglais. Enfin, nous établissons une distinction entre le sens descriptif et le sens évaluatif de l’équivalence, ce dernier étant considéré comme un synonyme de la fidélité qui, en traduction, est définie en tant que réussite ou échec pragmatiques (infidélité).

A significant number of airblast test have been carried out with the purpose to characterise and analyse the properties of improvised explosive device (IED) with non-conventional explosives in terms of knowing the effects on people and/or structures. Small devices with 1.5 kg of explosive, initiated with a detonating cord have been studied. Seven different mixtures have been tested with two types of ammonium nitrate AN (technical and fertilizer) in different forms like prills or powder. In some cases, the ammonium nitrate has been mixed with fuel oil while in others, it has been mixed with aluminum. The TNT equivalent based on pressure, impulse, arrival time, positive phase duration and shock front velocity have been calculated and analysed for each mixture. Comparing the field test data obtained with respect to the representation of the UFC 3-340-02 values, it can be seen that the parameters measured are consistent. The IEDs with fertilizer ammonium nitrate do not detonate with the present charge conditions so the shockwave generated is only due to the detonating cord. When using the technical ammonium nitrate, ANFO can partially detonate and generate a potentially dangerous shockwave. Finally, the IED with AN and aluminum produces a TNT equivalent close to one when the technical AN is used.

In order to investigate the damage influence of the leakage explosion in urban gas pipeline on the surrounding environment, the numerical models of buried PE (polyethylene) pipes under urban pavement were established by using ANSYS/LS-DYNA in this study. The reliability of the numerical models was verified on the basis of the explosion experiments. According to the amount of gas leakage, the TNT explosive equivalent was determined. The gas leakage explosion process of buried PE pipes was studied, and the pressure and stress changes of pipes and pavements under different explosive equivalents and buried depths were analyzed; at last, the deformation law of pipes and pavements were discussed. The results show that the PE pipes are fractured during the leakage explosion and a spherical explosion cavity is formed in the soil. The pavement above the explosion point bulges upward and forms a circle. The maximum pressure of pipe near the explosion point increases linearly with the increase of explosive equivalent, and a proportional relation is observed between the fracture width of pipe and the explosive equivalent. The degree and duration of pavement deformation increase significantly with the increase of explosive equivalents. The dynamic response of the pipes is rarely affected by the buried depth, and the change of maximum effective stress is no more than 7%. However, the buried depth is of great influence on the damage degree of pavement. When the buried depth increases from 0.9 m to 1.5 m, the pavement deformation can be reduced effectively. The variation rule of pavement deformation is similar to the change rule of maximum overpressure and effective plastic stress; they change in the form of concave functions with the increase of buried depth. The results can provide theoretical basis for municipal pipeline construction design and urban safety planning and provide references for the risk assessment of gas explosion in buried pipelines.

In the process of deciding upon an appropriate equivalent for a legal term, the translator can choose between several possible strategies. The goal of the article is to analyse the translation strategies of French and Czech legal terms that do not have a direct equivalent in accessible terminographic sources of the target language. Among the possible strategies, it deals in particular with literal translation, functional equivalence and descriptive. It observes that all of the three strategies are used, to a greater or lesser extent, by the analysed terminographic sources and seeks to point out the problems that the use of each of the previously mentioned strategies may cause.
