Pekka Pyykköng, the loss of triaxiality means that 1-parameter descriptions of stress and strain fields around crack tips may well be inadequate. Likewise near-by opposing cracks may lead to less ductility than expected from common tests..Stress and strain fields around static and growing creep cracks are reviePLIC 发表于 2025-3-23 23:25:20
