The radial (i.e., depth below the surface) dependence of the residual strain tensor within shot-peened samples of cylindrical geometry is measured nondestructively using high-energy synchrotron radiation (80 keV). Transmission geometry is employed in combination with a triangulation slit and area ...
Consider an infinitely extended elastic solid in which a domain {Ω:r ≤ a} is defined in cylindrical polar coordinates. The geometry of the problem is illustrated in Fig. 6.1 for a = 1. The problem is formulated in terms of letting the material within Ω experience eigenstrain ε∗=ε...

In the current model, εi includes phase transformation from parent phase to product phase or/and reorientation of martensitic variants. Assuming a unit directional vector n to show the average direction of oriented martensite variants, according to the traceless inelastic strain tensor, strain vector...

Standard cylindrical tensile samples (DIN 50125) with 4 mm in diameter and 20 mm in gauge length were machined along the rolling direction (RD) and the transverse direction (TD), respectively. In situ tensile tests were carried out at room temperature (RT) with an initial strain rate of 1.5...
The undrained shear strength of clay is sensitive to the strain rate. In addition, the strain-softening effect of soil strength reduction accompanied by large-scale shear deformation should be considered. In this study, anchor dragging simulations were performed for large-deformation analysis ...
