摘 要:研究了各向同性不可压缩超弹性Ogden材料组成的两种球形结构(实心球体和含有微孔的球体)在外表面拉伸载荷作用下的径向对称运动问题。给出了问题的基本控制方程和初边值条件,求得了描述球形结构运动的二阶常微分方程。通过对解的定性分析,证明了球形结构随时间的运动为非线性周期振动。The problems of radial symmetric motions are researched for two spherical structures ( namely, a solid sphere and a sphere with an initial micro - void) composed of a class of isotropic incompressible hyperelastic Ogden materials, where the structures are subjected to radial tensile loads on their outer surfaces. Firstly, we present the basic control equations and the initial and the boundary conditions of the problem, and obtain two second order nonlinear ordinary differential equations which describe the radial motions of the spherical structures. Through qualitatively analyzing of the solutions, it is proved that the structures would perform a nonlinear periodic oscillation with time.
