The Transient Thermal Stress in a Transversely Isotropic Infinite Solid with an External Crack

Abstract

The present paper deals with the transient thermal stress in a transversely isotropic infinite solid with an external crack subjected to heat exchange and heat absorption which depends on position and time. It is very difficult to obtain the analytical solution for the temperature field so that the finite difference method with respect to time variable only is introduced. Thermal stress is analyzed by means of transversely isotropic potential functions method. The numerical calculations of the stress intensity factor were carried out for a graphite which belongs under transverse isotropy. The effects of Biot numbers on the stress intensity factor are shown ion figures.
