A previous study of the behavior of friction in EHL contacts for the case of Eyring lubricant behavior resulted in a friction mastercurve. In this paper the same approach is applied to the case of limiting shear stress behavior. By means of numerical simulations the friction coefficient has been computed for a wide range of operating conditions and contact geometries. It is shown that the same two parameters that were found in the Eyring study, a characteristic shear stress, and a reduced coefficient of friction, also govern the behavior of the friction for the case of limiting shear stress models. When the calculated traction data is plotted as a function of these two parameters all results for different cases lie close to a single curve. Experimentally measured traction data is used to validate the observed behavior. Finally, the equations of the mastercurves for both types of rheological model are compared resulting in a relation between the Eyring stress τ0 and the limiting shear stress τL.

AbstractThe temperature dependent linear viscoelastic material behaviour of the most commonly used interlayer PVB is typically determined by means of Dynamic-Mechanical-Thermal-Analysis (DMTA). By horizontally shifting the isothermal modulus curves, a mastercurve is created at a certain reference temperature, which can then be mathematically approximated with a Prony series. A time–temperature superposition principle can be derived from the shift factors. In contrast to PVB, EVA and ionomer (or ionoplastic) interlayers have semi-crystalline structures that melt when the melting temperature is reached and form again when the sample is cooled below the crystallization temperature. The exact structure and number of crystallites depend e.g. on the cooling rate and the physical age (or thermal prehistory) of the sample. These factors must be taken into account in the experimental determination of the material parameters with DMTA. Using the example of SentryGlas®, this article shows that the stiffness of semi-crystalline interlayers is affected by the crystallinity. Mastercurves from DMTA with different temperature programs are created. The degrees of crystallization for the different temperature programs are determined with Differential Scanning Calorimetry (DSC). A time–temperature superposition principle, which applies to the purely amorphous material, and a time-crystallinity superposition principle are derived, which enable the determination of the material parameters for different temperatures and degrees of crystallization.

Practitioners and researchers in the paving industry have highlighted the importance of the adoption of reliability-based pavement design. The goal of developing reliable pavements with optimum performance over their design life has become a key factor to be considered during both pavement design and construction processes. This requires the adoption of statistical and probabilistic-based analyses for the formulation of the properties and behavior of pavement materials. Thus, many researchers worked on the quantification and modeling of the uncertainty caused by the inherent variability in pavement materials in general and that of asphalt concrete (AC) in particular. The dynamic modulus (| E*|), a fundamental property for mechanistic-empirical and purely mechanistic pavement designs, has been proven to have a significant level of uncertainty that is dependent on climatic and traffic loading conditions. The main objective of this study is to investigate the effect of the AC mixture properties and components on the uncertainty in the | E*| mastercurve. This objective is achieved by conducting an experimental program incorporating four different mixtures having the same material sources but different binder types and gradations. Monte Carlo simulations are used to model the uncertainty of | E*| for each of these mixtures. The paper shows that the uncertainty is dependent on mixture type, as the presence of larger nominal maximum aggregate size, modified binder, or additive can increase the uncertainty in the | E*| mastercurve, especially at high temperatures or slow loading rates. The uncertainty is proven to be material related and not imposed by the testing instrumentation.

Structural laminated glass elements are being used ever more frequently in the construction industry, following a growing architectural trend that looks for light and transparency. Nevertheless, an analysis of both regulatory and scientific state-of-the-art reveals several fields of inquiry which could benefit from deeper investigations. Namely, properties of plastics used as interlayer materials within the glass plies are scarcely investigated, professionals being far from unanimous on reliable techniques for comparing different materials on the same grounds. Yet, such knowledge is needed for reliable designs, especially in structural applications. This manuscript presents the results of a multi-scale experimental research on the mechanical response of three interlayers: PVB, SG and DG41. The former has been the standard in glass lamination industry, while the latter two are more recent and supposedly more performing from a mechanical point of view. The hyperelastic behaviour is studied with simple tensile tests on interlayer specimens; in the end, a novel generalized response model is proposed, which can be tuned to replicate the complex short-term and finite-strain response of any thermoplastic using few coefficients. Also, viscoelastic parameters of interlayers play an essential role in the global long-term laminated glass elements response. The temperature-dependent viscoelastic problem is investigated on a larger scale, using double-lap laminated glass joints under compressive loadings. Tests were performed on specimens made of three glass plies under long-term imposed actions in a temperature range between 0℃ and 60℃. An existing procedure was further developed, to provide insight on both creep and relaxation properties. Finally, calibrated Prony series for viscoelastic models are provided together with Williams Landel Ferry coefficients for time-temperature superposition, allowing to model the viscoelastic responses of the three interlayer materials at arbitrary temperatures. Limits and reliability of such models are discussed; simplified and ready-to use tables are provided. An analysis on the correlation between mechanical actions and loss of adhesion is performed. The third-level of the experimental analyses investigates the mechanical behaviour of progressively damaged, full-scale laminated glass beams. Risk analyses followed by fail-safe designs are often mentioned by standards and technical documents, but few studies have been carried out on the post-failure performance and effects of laminated beams made with tempered glass plies. After partial failure, the load-bearing capacity depends on the interlayers ability to generate coupling effects among fractured and undamaged glass elements through adhesion and its own mechanical properties. Results from dynamic and static tests are compared and the tension stiffening effect of interlayers in partially damaged elements is investigated. An equivalent thermal expansion is proposed to model the mutual effects which are generated among broken and intact plies in the event of partial failure. Further tests have been carried out in fully damaged conditions, to evaluate the residual load-bearing capacity and the effects of ageing such conditions. Uniaxial tensile and compressive test on fully damaged laminated glass specimens are performed. Results are used to model the response of fully damaged beams. In the last part of the manuscript, examples of application of newly found results are used in possible laminated glass structural designs: applications are provided for cold-bending techniques and post-failure safety assessments.

This paper intends to present the development of a Charpy V-notched (CVN) mastercurve to fit and/or extrapolate the transition curve of ferritic steels (including martensitic, bainitic and ferritic materials). The purpose of a mastercurve is to define a general mathematical model able to represent the overall behaviour: • of a material for different test conditions, • or for a set of materials for given tests conditions. The role of a mastercurve is then to allow extrapolating or interpolating values from other data on the basis of a robust model, thereby permitting to avoid execution of new tests. It is in general based on practical general observations and research for a common behaviour through a large database of experimental results. This kind of approach is largely used to fit fracture mechanics data and can also be used in the case of Charpy toughness. Some changes have to be performed in order to take into account specificities of Charpy (such as dependence of transition slope with strength of materials) as well as some verifications linked to statistical distribution of failure probability. This work is based on the assessment of a very large database collected for years at Industeel’s Research Center (tensile results, Charpy transition curves). This database represents 286 Charpy V-Notched transition curves of ferritic steels. It covers a wide range of materials and applications. Yield strengths of studied materials are ranging from 290 to 1180MPa while ultimate tensile strengths are in the range of 480 to 1690MPa. The target of this mastercurve is to predict the correct shape of the CVN transition curve with a reasonable safety margin on the basis of a limited amount of data (tensile properties at room temperature at least and when available, few Charpy data). A brief description of the database used within this study is given in the first part of this contribution as well as a description of the concept and underlying models. Finally, a validation of the work will be given as well as an illustration of its performance in a practical industrial case.

Asphalt concrete’s dynamic modulus (|E*|) is one of the key input parameters for structural design of flexible pavement according to the Mechanistic Empirical Pavement Design Guide (MEPDG). Till this day, pavement industry uses |E*| to predict pavement performance whether the material is hot mix asphalt (HMA) or warm mx asphalt or Reclaimed Asphalt Pavement (RAP) mixed HMA. However, it is necessary to investigate the correlation of |E*| with laboratory performance testing. In this study, laboratory dynamic modulus test was conducted on four different asphalt concrete mixtures collected from different construction sites in the state of New Mexico and mastercurves were obtained to evaluate dynamic modulus (|E*|) for a wide range of frequency. In addition, fatigue performance of these mixtures was predicted from the mastercurves and compared with the laboratory fatigue performance testing. Fatigue performance of these mixtures was evaluated from the four point beam fatigue test. The laboratory results show a good agreement with the predicted value from mastercurves. It is also observed from this study that the fatigue life of the asphalt concrete materials decreases with increase in |E*| value.

The newly developed mechanistic-empirical pavement design method uses the dynamic modulus as one of the crucial input parameters for the asphalt pavement to be designed or analyzed. This study proposes a new regression-based predictive model to estimate dynamic modulus of asphalt concrete from the viscosity of the asphalt binder used in the asphalt-aggregate mixture. Other parameters related to the aggregate gradation, such as, fineness modulus, and uniformity coefficient and the parameters related to the mixture volumetric are also incorporated in this model. A total of 21 asphalt concrete mixtures with asphalt binders having different performance grades and Superpave gradations were collected from different mixing plants and paving sites at various regions of New Mexico. The collected mixtures were then compacted, cored and sawed to cylindrical specimens. The asphalt concrete specimens were then tested for dynamic modulus at different temperatures and loading frequencies. The time-temperature superposition principle was then applied to develop dynamic modulus mastercurves at 70 °F (21.1 °C) reference temperature. The mastercurves were then fitted by the sigmoid function. The parameters of the sigmoid function were then correlated to the physical attributes of the asphalt concrete samples. Finally, a predictive model is developed to estimate the dynamic modulus of the AC mixtures typically used in New Mexico. Statistical evaluation showed that a fairly accurate estimation of dynamic modulus can be found by using this new dynamic modulus predictive model.

Abstract The complexities of designing an effective sand control for unconsolidated gas reservoirs in a deepwater environment is exacerbated when the targeted formation sands are characterized by particle size distributions with poorly sorted and non uniform coeficients, and high fine concentrations. Managing these intricacies requires comprehensive sand retention studies developed to ascertain the effectiveness of the sand control performance of gravel and screen gauge opening combinations in the presence of selected formation sand ratios. To build a representative testing program, actual core samples from the targeted studied zones are desirable. However, for economical, technical or logistic contrains the availability of these cores is not always feasible. This paper covers a workflow to determine a synthetic Particle Size Distribution (PSD) of a targeted well in a development block where no core data is available. The data feeding the workflow is derived from wireline bore hole imagers and Non-Magnetic Resonance (NMR) logs obtained from six wells drilled in the exploration phase of the studied gas block. Results are calibrated with localized PSD from available side wall cores. Furthermore, data obtained from the process is used to interrogate sand retention testing Mastercurves built with formation samples from one of the fields in the studied block (Field I). The interrogation process takes the synthetic PSD from the targeted well and creates normalized formation testing ratios which are then compared to the results documented on the sand retention Mastercurves. This paper is intends to discuss the worklflow and results of its field application.

In this study, field collected loose asphalt-aggregate mixtures were used to prepare cylindrical asphalt concrete specimen using a Superpave gyratory compactor and samples were subjected to four levels of aging. Unaged and aged samples were then tested for complex modulus, relaxation modulus, and creep compliance in the laboratory at different temperatures and loading conditions. To determine broadband characteristics, mastercurves of related viscoelastic material functions were determined by applying time-temperature superposition principle. A comparison study showed that increasing levels of aging have significant effect on viscoelastic functions of asphalt concrete. In addition, liquid asphalt binder corresponding to the asphalt-aggregate mixture was tested for complex shear modulus at various levels of aged conditions, using a dynamic shear rheometer. Results showed that even though the binder shear modulus increases significantly with aging, asphalt concrete modulus does not necessarily show similar increment.

Different material attributes such as mix volumetrics, aggregate gradations, and binder characteristics are the factors affecting viscoelastic material functions of asphalt concrete. In this study, the effects of aggregate gradation on the complex modulus function of asphalt concrete are determined. The two distinct properties of the aggregate blend considered in this study are the fineness modulus and the uniformity coefficient. A total of 54, plant produced, asphalt concrete mixtures with asphalt binders having various performance grades and sources were collected from the manufacturing plants. The asphalt-aggregate mixtures were then compacted, cored, and sawed to cylindrical specimens. Three cylindrical specimens from each of the asphalt-aggregate mixtures were prepared and tested in the laboratory for complex or dynamic modulus. After that, average mastercurves of complex modulus and phase angle were generated by applying time-temperature superposition principle. Study showed that the complex modulus function of asphalt concrete is significantly related to the fineness modulus and uniformity coefficient of the aggregate blends used in the asphalt-aggregate mixture.
