To simulate the full packaging process flow warpage and consider the influence of residual strain and stress at each step, the element birth and death technique is introduced to the finiteelement analysis
2、The FiniteElement Method Linear Static and Dynamic FiniteElement Analysis這本書出版較早,于2000年出版,是斯斯丹福大學Thomas教授的經(jīng)典之作,其中提出的許多概念到今日都還在使用,全書共計800多頁,值得仔細研讀。

為了簡化模型,筆者將書中損傷部分做了簡化,不再采用損傷屈服面進行判定。損傷影子w的計算直接由塑性等效應變確定。
