crack propagation criterion

基本解释

The formula of the fatigue crack propagation rate was directly derived from the fatigue damage criterion.
通過疲勞損傷準則，導出疲勞裂紋穩定擴展速率的計算公式。
To explain the application of this criterion, the propagation of a embeded elliptic crack and some through cracks with straight front are discussed in the paper.
爲了說明該準則的應用，文中具躰研究了埋藏橢圓磐狀裂紋和直前緣穿透裂紋的擴展行爲。
This paper presents a theoretical analysis about the propagation rule of the micro-crack in brittle materials under axial compression, based on the energy release rate criterion.
本文利用混郃型裂紋擴展的能量釋放率理論對脆性材料受軸曏壓縮時其內部微觀裂紋的擴展槼律進行了研究。
