Abstract: Plenty of geomechanics tests and theories have confirmed the existence of non-coaxiality while soil is subjected to principal stress rotation. This paper investigated the influence of one particular principal stress path, which is a ‘heart-shape’… read more here.

Abstract: Abstract Under seismic loading, soil layers experience multidirectional cyclic shear stresses with different amplitudes and frequencies. Therefore, the deformation behavior of soft clay under complex stress paths is practically relevant. In this study, cyclic tests… read more here.
