The element-free Galerkin method for dynamic crack propagation is described and applied to several problems. This method is a gridless method, which facilitates the modelling of growing crack problems because it does not require remeshing; the growth of the crack is modelled by extending its surface

A technique for modelling of arbitrary three-dimensional dynamically propagating cracks in elastic bodies by the Element-Free Galerkin (EFG) method with explicit time integration is described. The meshless character of this approach expedites the description of the evolving discrete model; in contra
## Abstract A timeβdiscontinuous Galerkin finite element method (DGFEM) for dynamics and wave propagation in nonβlinear solids and saturated porous media is presented. The main distinct characteristic of the proposed DGFEM is that the specific P3βP1 interpolation approximation, which uses piecewise
In the proposed element-free Galerkin method for deforming multiphase porous media, displacement of the porous-solid skeleton is modelled by standard finite elements while wetting and non-wetting fluid pore pressures are included as element-free nodes. The matrix formulation is derived from the vari
