A bifurcation problem on void formation and catastrophic growth was examined for a solid sphere composed of a class of transversely isotropic incompressible vulcanized rubber materials, where the sphere was subjected to a suddenly applied tensile constant load at its outer surface. A cavitated bifurcation equation that describes the formation and growth of a void at the center of the sphere is obtained. The effects of radial perturbation parameters on the solutions of the cavitated bifurcation equation are discussed. Stability, catastrophic phenomena of solutions and the actual stable state are analyzed by using the principle of minimum potential energy; meanwhile, numerical simulations are carried out.
