Stress Intensity Factors and Kink Angle of a Crack Interacting with a Circular Inclusion Under Remote Mechanical and Thermal Loadings

초록

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 (SlF) are investigated. The computed SIFs are used to predict the kink angle of the crack when the crack grows.
