This paper on "A Numerical Comparison of Post-Yield Fracture Criteria" was presented at the 3rd International Conference on Quality Assurance and Standards in Finite Element Analysis - 10-12 September 1991, Stratford-upon-Avon, England.

Summary

Three independent procedures for calculating parameters suitable for post-yield fracture mechanics using the finite element (FE) method are discussed and compared in three dimensional examples. The test geometries include wide plates with semi-circular or semi-elliptical surface cracks.
