Abstract
In this paper, an isotropic rectangular plate of finite width with a central circular hole has been considered. Plane stress finite element study under uniaxial, uniformly distributed, constant tensile loading, and temperature gradient has been carried out separately and validated. The combined study has been carried out by maintaining the temperature difference between two sides of the plate. By doing so it has been observed that the maximum stress occurring at the discontinuity getting reduced up to some optimum temperature (the temperature at which von Mises stress getting increased) after that it is crossing the maximum value of stress that had occurred in case of structural stress. As a result, the maximum reduction in SCF obtained is 13%. The optimum temperature value is different for different axial loading values.
