An adaptively refined XFEM for the dynamic fracture problems with micro-defects

•A new adaptively refined extended finite element method (VP-XFEM) is presented.•A multi-level, adaptively mesh refinement method is proposed.•The effectiveness and accuracy of the proposed method are verified.•The influences of micro-defects on the macro-crack propagating are analyzed. Micro-defect...
