Ah&met-Sib's fracture criterion based on strain energy density, S, for mixed mode crack extension under static loading is extended to dynamic mixed mode, K, and K,,, crack propagation. Influence of the second order term, uox, which represents the non-singular constant stress acting parallel to the d
The fatigue and fracture performance of a cracked plate can be significandy improved by reinforcing it with high modulus composite material. The reduction in valid fracture mechanics parameters like energy release rate (G) or stress intensity factor (SIF) is measure of effectiveness of the reinforce
A general method is given for calculating the energy release rate G from the local values of bending moments and loads in a cracked laminate. This total value is then partitioned into mode I and II components. Examples are given of the analysis of several test geometries including both variable and
