Experimental study on cavitation in rubber vulcanizates subjected to constrained tensile deformation

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