摘要(中)

本論文旨在反省現行文獻中，關於微孔形成理論一些可商榷之處。第一部分提出不穩定孔洞擴張有強烈與微弱的程度區別與不穩定擴張發生的難易程度及擴張速度的探討。接著再以模擬實際橡膠的各種不同材料模型比較，來探討實際橡膠材料的微孔不穩定擴張現象。
本論文第二個部分在探討圓形微孔非對稱變形的Hou-Abeyaratne Field(HAF)的精確性。

摘要(英)

This paper aims to reflect on the existing literature on microvoid formation theory can be open to discussion. The first part of the expansion of unstable voids have strong and weak degree of difference and the unstable expansion of the degree of difficulty and rate of expansion. Then a variety of material models to simulate real rubber to investigate the actual rubber material voids unstable expansion phenomenon.
The second part of this paper to investigate the non- symmetric deformation of the circular voids the accuracy of Hou-Abeyaratne Field (HAF).
