Модель трещины типа Дагдейла при смешанной моде нагружения (плоское напряженное состояние)

Abstract

A model of crack with a plasticity strip on its projection is proposed for the mixed loading by modes I and II. The unknown three stress components in the strip are determined from the plasticity condition, finiteness of stresses, and the established link among the normal stress components through the basic stress state. An analysis is carried out for the crack parameters under von Mises yield condition.
