利用特征方程展开方法，可获得分析裂纹尖端处二维热传导特征解的一维有限元列式。的英文翻译

基本释义

• By using the eigenfunction expansion technique, a one-dimension finite element formulation is then developed to determine the eigensolutions to the 2D heat conduction problem at the crack tip, which discretizes the sectorial domain circumferenially.
