The Transient Thermal Stress in a Transversely Isotropic Infinite Solid Containing a Penny-Shaped Crack

Abstract

The present paper is concerned with the transient thermal stress in a transversely isotropic infinite solid containing a penny-shaped crack with heat exchange on the crack surface. This problem is analyzed by means of the finite differences method with respect to only time variables and by the transversely isotropic potential functions method with respect to stress. The numerical calculations of the stress intensity factor were carried out for a graphite which belongs under transverse isotropy. The effects of the various anisotropies of the material properties on the stress intensity factor are shown in figures.
