Displacement Control Crack-Growth Instability in an Elastic-Softening Material .3. General-Analysis for a Small Softening Zone
The paper formulates a general criterion for the displacement control instability of a crack in an elastic-softening solid, with attention being focused on the situation where the softening zone size is small in relation to the solid’s characteristic dimension. The instability criterion is expressed in terms of the material’s softening behaviour and the solid’s geometrical parameters.
