Force-Displacement Response using the R-Curve

bullet

Increment the crack length from initial notch.

bullet

Use the R curve to compute the strain energy release rate at that crack length

bullet

Use energy balance , G = R, to solve for the applied load.

bullet

Iterate to satisfy the fiber pullout constitutive response across the crack length.

bullet

Obtain load-displacement- CMOD using compliance based approaches.

bullet

Propagate the crack to the next length, and continue to failure.
