A closed-form expression of the stress intensity factor is derived for a problem of straight crack in an infinite plate under thermal stresses induced by a temperature rise at an infinitesimal area. The present solution is applicable to wide range of uncoupled thermoelastic problems and is especially useful to understand the mechanical behavior of cracks in thermal stress cleaving (TSC). For instance, the present solution is useful for the prediction of an optimal temperature distribution in TSC, which is a function of various conditions such as shape of the plate, crack path, cleaving velocity and so on. Some basic problems of TSC formerly analyzed by the use of thermoelastic fields induced by a heat source were examined to confirm the applicability of the present solution.
