Evolution of Shear Band in Plane Strain Compression of Naturally Structured Clay with a High Sensitivity

The formation of the shear band is associated with failure soil. However, there has been relatively little investigation on evolution bands in naturally structured clay a high sensitivity. In this study, undrained plane strain compression tests, digital image correlation (DIC) analyses, and scanning electron microscopy (SEM) tests were performed to investigate characteristics clay. basic mechanical properties stress–strain relationships show that exhibits strong structure Compared under low confining pressure, more localized emerge specimens during pressures; however, when fail, only one fully developed, local deformation developed much larger than those other bands. Moreover, inside outside distinct discrepancies. SEM results micro-structures clays band, which are caused by development band. findings work provide new insight into
