β¦ Synopsis
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 constant ratio mixed mode tests. Solutions for compression failures with buckling are also given. Finally there is some discussion of specimen compliances and stability criteria for fixed load and fixed displacement.

Nuismer [1] derived an expression for the energy release rate G for mixed mode fracture in which case the initial angle of crack extension is not equal to zero, i.e. the crack extends in a non-self-similar manner. He developed a generalized relation in which G depends not only on the stress state be
