A hybrid approach to determine fracture resistance for mode I and mixed-mode I and II fracture specimens

This paper proposes a hybrid approach to determine the fracture resistance for mode I and mixed-mode I and II fracture specimens, combining both numerically computed and experimentally measured load (P) versus load-line displacement (LLD or Δ) relationships for metallic fracture specimens. The hybrid approach predicates on the same principle as the conventional, multiple-specimen experimental method in determining the energy release rate. The...
