Displacement control crack-growth instability in an elastic-softening material

Part I Linear elastic analysis for bend specimen configuration

Abstract

The criterion for a cusp catastrophe type of crack-growth instability in an elastic-softening material that is subjected to displacement control loading conditions has been investigated. Attention was focused on the behaviour of a material whose softening-zone size was very small in comparison with a solid's characteristic dimensions, because this facilitates a simple linear elastic analysis. Special consideration was given to the behaviour of an edge-cracked solid that was subjected to bending deformation, and the results complement those obtained by Carpinteri, who analysed the behaviour of an elastic-softening material which had a very large softening-zone size.
