Development of new fracture parameter for rigid inclusion with crack shape in creep material

크립재료의 균열형상 강체함유물에 대한 새로운 파괴역학 매개변수 개발

  • Published : 1997.12.01

Abstract

The analysis model is the infinite power law creep material containing the rigid inclusion with crack shape. The present analysis is performed using the complex pseudo-stress function method. The strain rate intensity factor is developed as new fracture mechanics parameter which represents the stress and strain rate distribution near a crack tip in power law creep material. The strain rate intensity factor is developed in terms of Kolosoff stress functions.
