Simple and robust element-free Galerkin method with interpolating shape functions for finite deformation elasticity

George Bourantas, Benjamin F. Zwick, Grand Joldes +2

In this paper, we present a meshless method belonging to the family of element-free Galerkin (EFG) methods. The distinguishing feature of the presented meshless method is that it a…
