Williams expansion-based approximation of the stress field in an Al 2024 body with a crack from optical measurements

Williams expansion-based approximation of the stress field in an Al 2024 body with a crack from optical measurements

A study on the approximation of the stress field in the vicinity of crack tip in a compact tension specimen made from Al 2024-T351 is presented. Crack tip stress tensor components are expressed using the linear elastic fracture mechanics (LEFM) theory in this work, more precisely via its multi-param...
