Once the is large than the the crack length growths. It is forward this existed a demarcation curve of the second crack below which this crack. However, as the second crack length beyond the demarcation curve both crack growth with different behavior the major crack starts with a smaller then accelerates the growth behavior to the simulation as the second crack length becomes under the demarcation curve at which the second crack stop its growing. en_US DC.subject 應力強度因子 zh_TW DC.subject 裂縫成長 zh_TW DC.subject stress intensity factor en_US DC.subject crack en_US DC.title 有限平板多條邊裂紋成長之探討 zh_TW dc.language.iso zh-TW zh-TW DC.title Study of the multi-cracks growth in a finite plate en_US DC.type 博碩士論文 zh_TW DC.type thesis en_US DC.publisher National Central University en_US
