Abstract

The dynamic and corresponding quasi-static stress intensity factors (SIF) generated by temperature change in an elastic space with a half-plane crack are calculated. An initial temperature of the space is constant, but on the crack edges there is a symmetrical heat exchange with the surroundings having a constant temperature which is different from the initial one. Comparison of the dynamic SIF and the corresponding quasi-static SIF shows that with rates of heat exchange being met in reality, dynamic effects and bound effects may be neglected. That fact facilitates the solution of the given problem to a great extent. 1 Introduction An isotropic massive solid (space) having a constant temperature T,, and having rather a great plane (or half-plane) cra
