Abstract:	本文將探討新虎克材料圓球的動力學反應，新虎克材料模型常用於模擬橡膠材料的力學行為，橡膠材料廣泛使用在建築物的避震器、輪胎、生醫工程材料等。本文研究橡膠材料球體含有微小孔洞分別受三種不同型式的脈衝荷重作用後使微孔的動態擴張，在脈衝荷重達一定強度後微孔迅速擴張，將形成材料結構上的弱化或破壞。本文將計算微孔在迅速且不穩定擴張時所達到脈衝荷重的臨界數值並定義之，並比較在不同形式的脈衝荷重作用時間下，材料弱化所需要的脈衝荷重強度以及其弱化嚴重程度。This paper will explore dynamics response of the sphere of the Neo-Hookean materials. Neo-Hookean material model commonly used in the simulation of mechanical behavior of rubber materials，and they are widely used in the vibration isolations, tires, bio-materials .In this paper, we discuss the rubber spheres, which contain micro-voids and they will dynamic expand by the three types impulsive loadings, porous rapid growth after impulsive loadings up to a certain intensity , it will make the materials’structure softening or destruction.This article will calculate and define the micro-voids’impulsive loadings critical values, which in the rapid and unstable expansion situation. And comparing different impulsive loading time, the materials needed the softening impulsive loadings intensity as well as its severity.
