Deformation of strain softening materials Part II: Modelling of strain softening response

This paper is an extension of the research reported by the authors in ref. [1]. The emphasis is placed on the modelling of unstable strain softening response. The inception of softening is viewed as a bifurcation problem. Necessary conditions for bifurcation corresponding to strain localization are first reviewed, followed by the description of post bifurcation behaviour. The approach advocated herein regards strain softening as a local …
