Abstract: The mesoscale structure generated in concrete plays a significant role in the mechanical properties and local failure behavior of mesoscale concrete. This work proposes a novel rigid-block discrete-element method (RB-DEM) ...

Abstract: This paper presents a contact parameter estimation method for collision modeling using discontinuous deformation analysis (DDA). Most DDA codes and discrete element method (DEM) codes use the viscoelastic contact model for ...

Abstract: This study aims to predict the undrained seismic bearing capacity and failure mechanisms of a shallow strip footing that is placed on homogeneous and heterogeneous cohesive soils above a single unsupported rectangular void ...
