Abstract:
A problem of a circular elastic inhomogeneity interacting with a crack under uniform loadings (mechanical tension and heat
flux at infinity) is solved. The singular integral equations for edge and temperature dislocation distribution functions are
constructed and solved numerically, to obtain the stress intensity factors. The effects of the material property ratio on
the stress intensity factor (SIF) are investigated. The computed SIFs are used to predict the kink angle of the crack when
the crack grows.
