Journal ArticleDOI
Meshless methods: An overview and recent developments
TL;DR: Meshless approximations based on moving least-squares, kernels, and partitions of unity are examined and it is shown that the three methods are in most cases identical except for the important fact that partitions ofunity enable p-adaptivity to be achieved.
Journal ArticleDOI
A coupled finite element-element-free Galerkin method
TL;DR: In this article, a procedure for coupling meshless methods such as the element-free Galerkin method with finite element methods is developed so that continuity and consistency are preserved on the interface elements.
Journal ArticleDOI
Continuous meshless approximations for nonconvex bodies by diffraction and transparency
TL;DR: In this paper, a diffraction method is proposed for non-convex meshless Galerkin meshes with cracks. But the results show only moderate imporvement in accuracy over the discontinous approximations, but yield significant improvements for enhanced bases, such as crack-tip singular functions.
Journal ArticleDOI
Element-free Galerkin methods for dynamic fracture in concrete
TL;DR: In this article, a mixed-mode dynamic crack propagation in concrete is studied using the element-free Galerkin (EFG) method, which allows for arbitrary crack growth in terms of direction and speed.
