Abstract: A series of biaxial (plane strain) experiments were conducted on three sands under low (15 kPa) and high (100 kPa) confining pressure conditions to investigate the effects of specimen density, confining pressure, and sand ...

Abstract: Digital imaging analysis was used to study localized deformations in granular materials tested under plane strain condition. Two independent techniques were applied and compared. In the first technique, the digitized optical ...

Abstract: Conditions for plastic localization, in terms of the possibility for discontinuous bifurcations of the incremental strain rate field, are given for the MRS‐Lade model. The susceptibility to bifurcation is examined along ...

Abstract: This study was carried out to assess the tensile and shear strength in lunar soil, and to examine the variation as a function of density and confinement. Geotechnical engineering properties of the lunar soil simulant ...

Abstract: In this paper, we investigate the behavior of elastic–plastic specimens during testing in a triaxial apparatus. In particular, an investigation of the influence of a number of imperfections on the observed behavior of a ...
