A three-parameter fracture criterion is applied to correlate fracture data from tensile cracked plates made of aluminum alloys. Fracture parameters to generate the failure assessment diagram are determined for the materials considered in the present study. Failure load estimates were found to be in good agreement with test results. The failure assessment diagram of a material generated from tensile fracture plate configurations can also be applied for failure pressure estimations of flawed pressure vessels.
