    Abstract: 宏觀的角度下,材料可使用連體力學來進行分析。然而,對於宏觀的材料弱化行為,分析時宜加入微觀的損傷行為計算以加深了解。
    ;In macroscopic scale,we usually use the concept of the continuum mechanics to analysis the behavior of the material.However,in order to analyze the weakening of materials,damages in micro scale must be taken into account.
    In this thesis,we will analysis the behavior of a micro void in a rubber block by using continuum mechanics and the finite element software(ABAQUS). For the deformations of a spherical micro-void,exact solutions and analytical approximate solution(the Hau-Abeyarantne field)had beed obtained.And we focus on the behavior of non-spherical micro-void in this thesis.we try to build up the relations between the visible shapes of an expanded micro-void and the invisible shape of the undeformed micro-void.Using these results we can infer about the shape of a undeformed micro-void from the observations of the expanded micro-void.The neo-Hookean model and the Ogden model are adopted in our study.
