Dynamic Analysis of the Damage Mechanism of Silt Lightweight Soil

Feng, Y. / Chen, Y. / Chao, Y.

This study aimed to systematically reveal the dynamic meso-scale deformation characteristics and damage mechanism of silt lightweight soil (SLS) from the Yellow River, China, under triaxial conditions. The improved three-phase random aggregates algorithm model, a new damage simulation method, and the expanded polystyrene (EPS) particles fixed-point monitoring technique were applied. It was found that EPS content, confining pressure, and the mechanical properties of the interface transition zone all affect the damage evolution process of SLS. Moreover, the propagation speeds of cracks also varied among different parts of the SLS. Four damage forms were defined based on the propagation speed of cracks.
