The following topics are discussed: Material behavior. Material tangent stiffness. Damage dissipation.

A Model for the Mullins Effect in Multinetwork Elastomers

The Mullins effect is a particular aspect of the mechanical response in filled rubbers, in which the stress–strain curve depends on the maximum loading previously encountered. The phenomenon, named for rubber scientist Leonard Mullins, working at the Tun Abdul Razak Research Centre in Hertford, can be idealized for many purposes as an instantaneous and irreversible softening of the stress–strain curve that occurs whenever the load increases beyond its prior all-time maxim… WebJul 1, 2012 · This phenomenon called Mullins effect has been observed in different paths of deformation during the last six decades.
