摘要
Abstract The paper presents an effective and accurate way to couple FEM meshes to peridynamic grids and uses it to solve 1D, 2D and 3D problems in static and dynamic conditions. Crack propagation with crack branching problems is also solved. An adaptive algorithm is presented which allows to transform FEM nodes into peridynamic nodes. In this way a new computational technique is produced which equips standard FEM with the capability to effectively and efficiently describe 3D problems with crack propagation phenomena.
