.... Detailed vertical and lateral stress distributions for different bearing plates were determined which help in understanding the impact of bearing plate properties on the behavior of the prism. The results show that a 51 mm (2 in.) thick steel bearing plate for a 203 mm (8 in.) block prism is inadequate...

..., strains, and strain rates are derived and are used to obtain the local true stress-true strain curves. These are corrected for the change in strain rate with strain using an equation of state. The corrected curves are in good agreement with published curves on similar steels determined by compression...

...R Mott; G Huber; A Leewood An experimental investigation was conducted to develop a test method and hardware for the purpose of characterizing the material behavior of coated glass fabrics for application in large roof structures. Because of the biaxial nature of stresses in fabric structures...

...MS Mamlouk; YM Yuan; NT Tseng; GC Lee The Marshall method is one of the most common techniques used in the design of asphalt concrete mixes. However, the structural behavior of the asphalt concrete specimen during the Marshall test is not clearly understood. In this study the stress distribution...

...UC Jindal; ML Mandal Scientific and technical literature is full of research papers on the investigations of stress concentrations around holes and rows of holes in plates. All these stress concentrations have been determined in specimens where the stresses and strains away from the holes are well...

.... Linear elastic material behavior and plane stress conditions are assumed to hold in the finite element analysis of the Marshall testing procedure. The elastic modulus required for this analysis is obtained from a separate unconfined compression test on long cylidrical specimens made of the same asphalt...

...TM Proctor, Jr Ultrasonic measurements of the variation of elastic modulus with stress have been done for more than 30 years. The inverse problem of measuring residual stress by ultrasonic means is still poorly understood. As a result, the measurement of residual stress by ultrasonic means has...

A fundamental calibration parameter of the new technique is the stress acoustic constant defined as the fractional change in the resonant standing-wave frequency in the solid cavity...

...P Yavari; TG Langdon A simple constant stress tensile creep machine is described for use at very low stress levels. The initial mechanical advantage of the machine is 3:8 and the minimum feasible load is about 1.8 N. Some typical creep results are presented for an aluminum-5% magnesium alloy...

...AJ Bush Dimensionless stress intensity factors were determined for single-edge-crack solid and hollow round bars loaded in tension. These factors were calculated from experimental compliance (inverse slope of load-displacement curve) measurements made over a range of dimensionless crack depths...

... under general multiaxial loading at room temperature. The survey indicates that the early development of the criteria was based on extensions of static yield theories to fatigue under combined stresses. These are stress-based criteria limited primarily to high-cycle fatigue. Most of the later criteria...

...K Ikegami An optimal test method to determine the anisotropic parameters of the yield condition under a combined stress state is proposed. Because scattering of experimental values affects the calculated results, the combined stress tests should be conducted under conditions that minimize...
