Closing Curved Crack in the Sheet Element under Action the Local Temperature Field

Abstract

Local changes of temperature near to the end of a curvilinear crack are considered. The problem about balance of a curvilinear crack with in part contacting beach at action of the external stretching loadings, induced thermoelastic fields of stresses and efforts on contacting surfaces of a crack in each approach, is reduced to system singular the integrated equations. Contact stresses, values of the sizes of end contact zone where beach of a crack are closed are found normal and tangents.
