Abstract:

The penetration of projectiles into semi-infinite targets helps in the understanding and modelling of terminal ballistics. The article describes field test results of 5.56×45 mm F1 Ball and 7.62×51 mm M80 Ball ammunition. The targets were 25-mm-thick mild and high strength steel plates of Grade 250 MPa and 350 MPa, respectively. The tests recorded penetration depth, muzzle and impact velocities, and bullet mass. Despite its smaller calibre, the 5.56 mm × 45 mm F1 Ball ammunition recorded deeper penetrations than the larger calibre 7.62 mm × 51 mm M80 Ball ammunition. This is due to the 5.56 mm ammunition comprising a hardened steel penetrator and lead core, whereas the 7.62 mm ammunition comprised only a lead core. Multiple shots were fired for each type of munition. The coefficient of variation of steel penetration is approximately 0.10 and 0.03 for 5.56 mm and 7.62 mm rounds, respectively. The article also presents predictive models of steel penetration depth and compares these to the field test results.

Full text

Abstract:

Nanobodies are well-established targeting ligands for molecular imaging and therapy. Their short circulation time enables early imaging and reduces systemic radiation exposure. However, shorter circulation time leads to lower tracer accumulation in the target tissue. Cell-penetrating peptides (CPPs) improve cellular uptake of various cargoes, including nanobodies. CPPs could enhance tissue retention without compromising rapid clearance. However, systematic investigations on how the functionalities of nanobody and CPP combine with each other at the level of 2D and 3D cell cultures and in vivo are lacking. Here, we demonstrate that conjugates of the epidermal growth factor receptor (EGFR)-binding nanobody 7D12 with different CPPs (nonaarginine, penetratin, Tat and hLF) differ with respect to cell binding and induction of endocytosis. For nonaarginine and penetratin we compared the competition of EGF binding and performance of L- and D-peptide stereoisomers, and tested the D-peptide conjugates in tumor cell spheroids and in vivo. The D-peptide conjugates showed better penetration into spheroids than the unconjugated 7D12. Both in vivo and in vitro, the behavior of the agent reflects the combination of both functionalities. Although CPPs cause promising increases in in vitro uptake and 3D penetration, the dominant effect of the CPP in the control of biodistribution warrants further investigation.

Full text

Abstract:

A traditional penetration test only measures the total penetration within 5 s. The penetration process is not monitored, and therefore, a large amount of information on the deformation properties of asphalt is not used. This paper documents a study to use a high-speed camera to quantify the entire penetration process and use the Finite Element Method (FEM) to interpret the penetration process using a viscoelastic model. The penetration–time relationships of several asphalt binders (70#, 90#, a rubber modified binder, and a styrene-butadiene-styrene (SBS) modified binder) have been acquired using the new method, and the FEM modeling of the penetration processes is performed. The results show that both stress relaxation and creep appear during the penetration process. The results indicate that the improved test method and its data interpretation procedure may better characterize the properties of asphalt binder, which may extend the applications of the traditional penetration test.

Full text

Abstract:

The standard penetration test (SPT) split-spoon sampler is too small for investigations in gravelly soils. For this reason, several researchers have developed scaled-up versions of the SPT, commonly referred to as "large penetration tests" (LPT), and attempted to correlate the measured blow counts to SPT blow counts. Several LPTs have been in use worldwide; each with different drill rods, sampler dimensions, and hammer energies; hence existing published LPTSPT correlations differ for each system. This paper summarizes the LPT data in the literature and presents a fundamental method for predicting LPTSPT correlations. The proposed method is based on wave equation analyses of SPT and LPT and considers variations in test equipment, penetration resistance, and energy. It is shown that the method provides a unified approach for assimilating the various published LPTSPT correlations. Additional SPT and LPT data were collected at a sand research site to check the proposed method and to expand the LPT database. The observed and predicted correlation factors are shown to be in good agreement. The proposed correlation method will be useful as a logical framework for the comparison of LPT data collected throughout the world. Additional research will be required to extend this procedure to gravel sites.Key words: large penetration test, LPT, fundamental correlation method, wave equation analysis, grain size effects.

Abstract:

In this paper, the penetration characteristic of tungsten penetrator was studied. Tungsten and aluminum was used as the material of the penetrator and target, respectively. Dimensions of the aluminum target were 100 X 100 X 5 (mm3). The penetrator with cylinder conical tip and flat tip was used in the impact test and simulation. The range of the initial velocity was from 400 to 1600 m/s. The angle of the incidence on the penetrator with cylinder cone tip was 0 ̊. The angle of the incidence on the penetrator with flat tip was 0 ̊, 30 ̊ , 60 ̊ . To obtain results of the simulation, AUTODYN 3D code was used. The residual mass and velocity was obtained to compare with results between the impact test and simulation.

Abstract:

AbstractThis introductory lecture discusses the international use of the standard penetration test (SPT) and presents the proposals for International Reference Test Procedures. The application of the SPT as a means of assessing the strength and stiffness of weak rocks is mentioned together with the reliance upon the test at the present time for estimating the liquefaction potential of saturated fine grained non-cohesive soils. The various aspects of the execution of the SPT are discussed which can provide variable and unrepresentative values of resistance (N values).The principle of measuring energy losses and making adjustments to the N values is introduced as a basis for ensuring comparability of test results.Reference is made to the general descriptions of the SPT given in BS 5930:1981 and to the lack of clear guidance in this British Standard.

High-g accelerometer and storage test system is designed for the measurement of multi-layer steel targets penetration. The penetration test of the double layer steel target is performed, and the verload acceleration is obtained when the projectile penetrates the steel target. According to the overload data, the effective overload accelerations are concluded. The effective overload accelerations gained when projectile penetrates the double steel targes are 81078g and 152061g respectively. Also from the calculation, it can be concluded that the test errors are all less than 10%, which can meet the requirement of penetrating multi-layer steel targets.

Abstract:

Background The double blind, non-penetrating placebo needle is effective in masking patients who are not informed that they may receive a placebo needle. In this study, we aimed to examine whether such needles are effective in masking subjects who have been so informed. Methods One hundred and fourteen informed, consenting, healthy volunteers were recruited. An experienced acupuncturist applied one of the following needle pairs – penetrating/non-penetrating, non-penetrating/non-penetrating, penetrating/penetrating – randomly at bilateral TE5 points in subjects who were informed that they would receive either a non-penetrating or a penetrating needle. After the application of a pair of needles, the subjects reported for each arm on whether they identified the needle as non-penetrating or penetrating. The patients also rated skin penetration/penetration-like pain and the deep dull pain ( de qi) associated with the needle application on a visual analogue scale (VAS). The chi squared goodness of fit test was used to determine the probability of the number of correctly and incorrectly identified needles. Statistical comparisons for VAS scores for skin penetration pain and de qi were made using Mann-Whitney's U test. Results Of the 114 non-penetrating needle applications, the subjects identified 64 incorrectly and 50 correctly, fitting a probability of 0.5 (χ2=1.72, P=0.19). Most interestingly, the subjects identified 36 (32%) of 114 penetrating needle applications incorrectly. Skin penetration/penetration-like pain and de qi scores did not differ significantly (P=0.87 and P=0.17, respectively) between the 114 non-penetrating and 114 penetrating needles. Conclusions The non-penetrating placebo needle was effective in masking fully informed subjects. When used together with the matched penetrating needle, it has potential for use in double blind (patient and practitioner blind) studies.

Abstract:

This article is the first of a two-part series. The second article titled "Investigations of Particle Penetration in Fibrous Filters, Part II. Theoretical" will appear in the upcoming March/April 1998 issue of the Journal of the IEST. The performance of high-efficiency filters is evaluated using a semiautomated test system. This system is used for accurate measurements of submicron particle penetrations and pressure drops of filters. The system is designed to minimize errors and uncertainties associated with filter testing procedures. New commercial filter media, rated from ASHRAE-grade to ULPA, are tested using this system. The particle penetration characteristics of these media are obtained at different face velocities, ranging from 2 to 20 cm/s (0.79 to 7.9 in/s), and the particle diameter is varied from 0.05 to 0.05μm. The efficiencies of these media range from 15 percent to 99.9999 percent. The particle penetration characteristics of the media are consistent with the theories of collection by diffusion and interception in the range of operating conditions studies. The presence of the most penetrating particle size is observed, varying from 0.1 to 0.3μm for the different media. The most penetrating particle size is shown to shift toward the smaller particle size for increasing face velocity.

Abstract:

Computerized MS-Windows Visual Basic software of a cone penetration test (CPT) for soil classification was developed as part of an extensive effort to facilitate the implementation of CPT technology in many geotechnical engineering applications. Five CPT soil engineering classification systems were implemented as a handy, user-friendly, software tool for geotechnical engineers. In the probabilistic region estimation and fuzzy classification methods, a conformal transformation is first applied to determine the profile of soil classification index (U) with depth from cone tip resistance (qc) and friction ratio (Rf). A statistical correlation was established in the probabilistic region estimation method between the U index and the compositional soil type given by the Unified Soil Classification System. Conversely, the CPT fuzzy classification emphasizes the certainty of soil behavior. The Schmertmann and Douglas and Olsen methods provide soil classification charts based on cone tip resistance and friction ratio. However, Robertson et al. proposed a three-dimensional classification system that is presented in two charts: one chart uses corrected tip resistance (qt) and friction ratio (Rf); the other chart uses qt and pore pressure parameter (Bq) as input data. Five sites in Louisiana were selected for this study. For each site, CPT tests and the corresponding soil boring results were correlated. The soil classification results obtained using the five different CPT soil classification methods were compared.

Abstract:

Penetration efficiency reflects high speed projectile penetration ability with the impact velocity (>800m/s) variation. To further study the penetration efficiency engineering model, the physical and mechanical parameters that affect the penetration efficiency of high-speed projectiles penetrating into concrete target are analyzed, penetration efficiency dimensionless quantities are determined, such as projectile’s length to diameter ratio, projectile and target strength ratio, etc. The dimensionless equation of penetration efficiency is got by using the homogeneous principles of the laws of physics dimensionless. According to experimental data, a function of dimensionless penetration efficiency and dimensionless projectile speed is fitted. Finally, the model is verified by test, and the model calculations and experiment results agree well. The model obtained in this paper can estimate the projectile’s impact velocity when the penetration efficiency reaches the maximum, it would be a theoretical guidance for high speed penetration effects experiments.

Abstract:

Design of building structure always related to the foundation, field testing is often done to test the bearing capacity of the soil in the form of a cone penetration test (CPT) and a standard penetration test (SPT). From the two field tests that are often done, it is necessary to research the amount of bearing capacity obtained through CPT and SPT data. This study uses a bearing capacity analysis of the pile foundation using CPT and SPT data in Pesanggaran, Bali, Indonesia. The analysis was carried out by comparing the bearing capacity of pile foundations using pile foundations with dimensions of 15 cm, 20 cm, 25 cm and 30 cm at a level of 10 meters. The results of the bearing capacity percentage are then compared. From the analysis conducted, the bearing capacity of pile foundations using CPT data has a higher value than the carrying capacity of poles using SPT data with a bearing capacity difference of 10,4-16,3%.Perancangan suatu struktur erat kaitannya dengan fondasi, pengujian lapangan yang sering dilakukan untuk mengetahui daya dukung fondasi berupa cone penetration test (CPT) dan standard penetration test (SPT). Dari dua pengujian lapangan yang sering dilakukan, maka perlu dilakukan dilakukan penelitian mengenai seberapa besar perbedaan hasil daya dukung yang diperoleh melalui data CPT dan SPT. Penelitian ini melakukan perbandingan analisis daya dukung fondasi tiang dengan menggunakan data CPT dan SPT di Pesanggaran, Bali, Indonesia. Analisis dilakukan dengan membandingkan daya dukung fondasi tiang menggunakan fondasi tiang berdimensi 15 cm, 20 cm, 25 cm, dan 30 cm pada kedalaman 10 meter. Hasil persentase daya dukung yang diperoleh kemudian dibandingkan. Dari analisis yang dilakukan, diperoleh daya dukung fondasi tiang menggunakan data CPT memiliki nilai lebih tinggi daripada daya dukung tiang menggunakan data SPT dengan perbedaan daya dukung 10,4-16,3%.

Abstract:

The paper presents two methods for in situ testing of strength and creep properties of ice, together with their theoretical interpretation and typical results. The two methods which are relatively new in this area of application, are the stress-controlled cone penetration test (CPT), and the sharp cone test (SCT). The CPT has been shown in the last few years to be an excellent tool for both ice quality profiling and ice creep and strength properties determination. The test can be used for penetrating vertically through an ice sheet, or laterally into an ice wall in a trench. The SCT is a special kind of borehole-expansion test. The method consists in pushing a smooth, low-angle, conical indentor into a predrilled conical portion of a borehole, which ends with a smaller diameter pilot hole. The creep properties of ice are then deduced from the relationship between the applied load, time, and cone penetration, which is directly related to the hole expansion. Key words: ice, creep, strength, in situ testing, cone penetration, borehole expansion, sharp cone.

Abstract:

Do tests to study anti-penetration performance of ceramic multi-layer composite medium structure with simulation method of a 1:5 shrinking model and analyze its mechanism. The result shows that ceramic composite layers, which are composed by glass reinforced plastic materials and ceramic materials, obviously consume quality and kinetic energy of penetrating shot body. And the smaller biting angle of shot body is, the more serious damage of structure will be.

Abstract:

Sunjoto developed shape factor equations in order to determine the drawdown and hydraulic conductivity value. Many researchers had conducted research using these equations under the pump test. Moreover, most of the research used Sunjoto equations as the comparison with the other pump test equations. Since 1951, shape factor equations have been developed to determine hydraulic conductivity value under slug test which mainly focus on the dimension of well. Afterwards, many scientists and researchers developed shape factor equations including Sunjoto, Bouwer and Rice. Therefore, this research intends to use Sunjoto equation under the slug test. The comparison of hydraulic conductivity by constant head test and slug test has been conducted in this research. The comparison value is acceptable although there are difference values that were caused by disturb and Un-disturb sample.
