WebbOur 3-D formulation using hexahedron elements rigorously embraces a posteriori error estimation scheme, a structural coupling scale-meshes strategy and an enrichment technique. Remeshing is only performed where it is needed, e.g., a vicinity of crack, through an error estimator based on the recovery stress procedure. WebbThe shape functions for this cubic tetrahedron element in the volume coordinates are given as follows: (9.65) where Li is the volume coordinate, which is the same as the shape …
