A cyclic elasto-plastic constitutive model for sand considering a plastic-strain dependence of the shear modulus
A cyclic elasto-plastic constitutive model based on a non-linear kinematic hardening rule for sand is proposed. Three points are incorporated into the model: a new flow rule, a cumulativeExpand

Estimating the impact force generated by granular flow on a rigid obstruction
Flowing sediments such as debris and liquefied soils could exert a tremendous amount of force as they impact objects along their paths. The total impact force generally varies with slope angle,Expand
