| Abstract: | The finite ocsillation of a transversely isotropic incompressible hyper-elastic hollow sphere with the neo-Hookean strain energy function, subjected to a suddenly applied uniform radial tensile boundary load, is studied following the theory of finite deformation dynamics. An exact differential relation between the maximum amplitude and the tensile load is obtained. The phase diagram for the nonlinear periodic oscillation and the approximate period are obtained too. The phase diagram for the oscillation, the maximum amplitude and the approximate period depend on the degree of anisotropy of materials. |
