Three-dimensional numerical manifold formulation with continuous nodal gradients for dynamics of elasto-plastic porous media

A three-dimensional (3D) numerical manifold formulation with continuous nodal gradients (H8-CNS) is presented for dynamic analysis of saturated elasto-plastic porous media based on the three-variable (u−w−p) formulation. Using meshes of 8-node hexahedra as mathematical patches, the skeleton displace...
