Mode-mixity in numerical simulation of FRMM test: local partitioning using cohesive zone

Fixed-ratio mode-mixity tests were numerically investigated using various cohesive zone properties. The deformation energy (mode I and mode II fracture) going into cohesive elements is monitored and fracture mode-mixities for different configurations are calculated and compared to existing analytical partitioning theories. Opposite to the theories, partitioning is observed to be property dependent.
