Abstract

Abstract: Advanced experimental techniques in terms of in situ dilatometry and X‐ray microtomography as well as microscopy have been used to investigate cavitation in unfilled and carbon black reinforced styrene‐butadiene rubber vulcanizates. The work introduces into the features of multiaxial deformation and damage behavior characterized by the formation and growth of internal defects – so‐called cavities . Experimental evidence indicates that cavitation damage occurs in rubber vulcanizates subjected to constrained tensile deformation, while the number of cavities is increasing, but the average cavity size is decreasing with increasing degree of constraints.
