本文探討橡膠材料中微小孔洞的擴張情況。我們使用兩種方法,一種是有限元素法(FEM),一種是Hou-Abeyaratne Field (簡稱HAF),並比較這兩種方法所計算出的解,以有限元素法所計算出的解為基準,來計算HAF與FEM之間的誤差。 This paper discusses the void growth in the rubber material. We use two methods, one uses the finite element method (FEM), one uses the Hou-Abeyaratne Field (HAF), and compare the two solution which calculated from FEM and HAF. The differences between these two solutions are calculated.
