Investigation of Effective Parameters on Stress Distribution around Non-Circular Hole Under Thermal Source

In this paper, based on the theory of two-dimensional thermo-elasticity steady state, the influence of parameters affecting stress field created around a non-circular hole in an infinite isotropic plate under a heat source is investigated. The isotropic plate has a point heat source near the hole and the boundary of the hole is insulated. By using the complex potential functions and applying conformal mapping and solving the integral equations, stress distribution around the hole is represented. The used method is the expansion of the complex variable method for an infinite isotropic plate with circular and elliptical holes. Bluntness and rotation angle of the hole are important parameters that are considered in this research. The results of this study show that the bluntness parameter has a significant effect on the stress distribution around the holes and near the heat source.
