WebMullins effect; there is evidence to suggest that the Mullins effect occurs in unfilled as well as filled rubbers (see Rigbi (1980) and Johnson & Beatty (1993a) for refer-ences). Since the material response is governed by different forms of strain-energy function on primary loading and unloading, we refer to the model as pseudo-elastic. WebThe Mullins effect describes a phenomenon typical for rubber materials. If a stress - strain curve is recorded for a strip sample, by means of a program such as the Universal Test …

WebNov 22, 2016 · Both effects were recently reported on a new kind of synthesized tough gel, with capability of large deformation, high strength, and extremely high toughness. In this work, we develop a coupled viscoelastic and Mullins-effect model to characterize the deformation behavior of the tough gel. WebThe Mullins effect model in ABAQUS assumes that the damage is associated with the deviatoric behavior only. The disc has an outer diameter of 3 inches, an inner diameter of 1.75 inches, and a thickness of 0.7 inches. The inner surface of the disc is fully constrained. The outer surface is initially defined to be just touching a flat rigid surface.
