Influence of Constrained Tensile Deformation on Cavitation of Rubber Vulcanizates
Abstract
Durability of rubber compounds, such as crack resistance, is one of the essential characteristics required to tires, for sake of safety. Mechanism underlying crack propagation of rubber vulcanizates is explored in terms of void formation and growth in the rubber matrix. Extensive X-ray and dilatometry analysis revealed that the rubber matrix at the crack tip undergoes “multi-axial” constrained tensile deformation, causing the void formation.
