After testing, the particle size variation of coral sand was also analysed to explore the law of particle breakage that incorporates the effects of intermediate principal stress and cross-anisotropy. Test results show...

To address this, a novel sample preparation method for true triaxial tests has been developed, allowing the BP to rotate around the major, intermediate and minor principal stress axes, enabling the measurement of the strength anisotropy across all...

Analysis of anisotropy for unsaturated soils is a less explored topic, both from experimental and constitutive standpoints. This works...

An original concept of moving critical state is elaborated by a novel state parameter-based rotational hardening rule that is subsequently used...
