New model materials made of laser drilled copper sheets have been fabricated to study the ductile fracture process. Inβsitu tensile tests in a scanning electron microscope and in an XβRay computed tomography setβup allows us to observe the void growth and coalescence in 2D and 3D. It is shown that t
## Abstract The meshless elementβfree Galerkin method (EFGM) is considered and compared to the finiteβelement method (FEM). In particular, topological aspects of meshless methods as the nodal connectivity and invertibility of matrices are studied and compared to those of the FE method. We define fo
