Stress intensity factors for cusp-type crack problem under mechanical and thermal loading

Abstract The general solutions of the stress intensity factors (SIFs) for a cusp-type crack problem under remote uniform mechanical and thermal loads are presented in this work. According to complex variable theory method conformal mapping, symmetric airfoil is mapped onto unit circle, both temperature potentials used solve relevant boundary-value problems. By introducing auxiliary function applying analytical continuation theorem, SIFs at tip can be analytically determined. obtained SIF results dependent on geometric configurations components magnitudes loads. For some combinations combined loads, maximized, system has high risk damage.
