The J-integral criterion for initial crack growth is discussed. It is pointed out that an essential requirement for the validity of this criterion is autonomy of the end-region near the crack-tip. This autonomy ought to exist even at large scale yielding if there is a substantial strain hardening, i
Ah&act-The deformability of ductile materials in tension is restricted by the initiation and growth of voids and by their final coalescence into a crack. In this paper, a model is proposed to calculate the stress vs displacement curve of a volume element comaining a growing void, which takes into ac
The effect of the ratio a/W on the values of si and Ji in a structural steel has been studied by measuring the crack opening displacement and J-integral at initiation of crack growth in three-point bend specimens with shallow and deep notches and by three-dimensional finite element method analysis.
