文摘
- •
A novel adaptive XFEM using hexahedron elements for inclusions and voids of composite materials is presented.
- •
A posteriori error estimation based on recovery strain allows ones to obtain a desired accuracy with one or two trials.
- •
Variable-node hexahedron transition elements are used to treat the mismatching problems of different meshes.
- •
Single and multiple inclusions and voids in composites are modeled accurately and efficiently.
