Three-dimensional finite-element analysis including elastic-plastic material response
… Three practical applications are presented. The thick-walled cylinder under internal pressure and the transversely loaded thin plate on simple supports are analyzed under the assumption of ideal plasticity. Comparisons with existing solutions are also made. For the third example, an …

An experimental investigation into the stress-dependent mechanical behavior of cohesive soil with application to wellbore instability
… make use of two new automated, high pressure Thick-Walled Cylinder (TWC) devices to study the effects of the following parameters on the borehole response: mode of loading, specimen geometry, preshear lateral stress ratio, drainage conditions, consolidation stress level, stress history, and …

Wellbore instability mechanisms in clays
… lab experiments are performed on high pressure Thick- Walled Cylinder (TWC devices) using RBBC as analog testing material (Abdulhadi, 2009). The MIT-E3 predictions demonstrated a very good match with results from the experiments. The results from the analyses illustrated the effect of the device …

CFRP Prestressed Concrete Exposed to Moisture
… rods in water, contrary to the prediction of the thick-walled cylinder model, but possibly caused an increase in the CFRP-concrete radial contact pressure. The imposition of sustained bending stresses on wet CFRP rods was found to cause premature failure, believed to be a result of matrix …

Analysis of Adiabatic Shear Banding in a Thick-Walled Steel Tube by the Finite Element Method
… analyzed numerically for an impulsively loaded thick-walled steel tube. A circumferential V-notch located at the outer surface of the center of the tube provides a stress concentration. The material is modeled as strain hardening, strain-rate hardening and thermal softening. The dynamic loading …

Design and Multi-physical Fields Analysis of High Speed Permanent Magnet Machines
… the research and analysis for HSPMM. <br/>Then, thick-walled cylinder theory is introduced to study rotor mechanical strength analytically, while it also verifies the FEM calculation results. Then based on FEM analysis, HSPMM rotor stress distribution is investigated with sleeve material effects …
