橡膠材料中孔洞擴張會導致材料的弱化，所以研究孔洞的擴張有助於了解橡膠的行為。目前的研究大部分以單孔問題為主，本文則研究孔與孔之互制問題，觀察其應變集中的現象，即孔洞軟化之行為。與孔洞相互位置及大小尺寸之關係。; The growth of voids in rubbers can cause strength degradation of the materials. So, the studies of void expansions in rubbers can facilitare the understanding of the behavior of rubbers. The current researches mostly concentrate on the growth of a single void, and our research ideas with the void interaction problem. We clarify the effects of void sizes and positions on the strain concentration and softening of the void.
