Abstract:The purpose of this paper is to show a highly accurate inverse analysis for the problem of lozenge cavity with sharp corner under in-plane and out-of-plane loadings, which is based on the complex variable method using a conformal mapping technique. A method of inverse analysis for the magnitude and direction of initial stresses is represented by use of the exact elastic solutions. The results of inverse analysis are in agreement with the analytic results on high accuracy. Key Words:elasticity, inverse analysis, Lozenge cavity, exact elastic solution, stress concentration, In-phase and out-of-phase loadings
