UNIFIED FORMULATION OF J-INTEGRAL FOR COMMON CRACK TYPES USING GENETIC PROGRAMMING
This study proposes Genetic Progran1ming (GP) as a new tool for the analysis and formulation of the J-integral for theopening mode offracture mechanics. The proposed GP formulation is based on extensive Finite Element (FE) results. AGP based I-integral formulation for the three different geometries w
