Abstract

This paper examines the behaviour of two elasto-plastic fracture parameters which characterise the severity of a crack-tip field under large scale yielding. One may be regarded as a local crack-tip parameter which associates closely to the stress/strain fields at the crack-tip whilst the other may be considered as a far-field parameter. Several centre-cracked and edge-cracked plates were analysed under various loading and unloading sequences, and it was found that such parameters can be of significant use in explaining the effects of prior plastic deformation in fracture problems.
