Many rubber-like materials consist of a cross-linked elastomers substance with a distribution of small carbon particles as fillers. A piece of filler loaded rubber subjected to a series of loadings typically displays pronounced stress softening associated with damage. This stress softening phenomenon is referred to as the Mullins effect. The effects of strain history on the stresses and the formulation of constitutive models for filled and unfilled elastomers have been a particular focus of attention during the last few years. In this general remark, some representative damage functions are compared and two examples of permanent set are showed with maximal use of user-subroutine.
