crack propagation criterion

基本解釋

The formula of the fatigue crack propagation rate was directly derived from the fatigue damage criterion.

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(wèi)了說明該準(zhǔn)則的應(yīng)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(kuò)展行爲(wèi)。
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(kuò)展的能量釋放率理論對脆性材料受軸曏壓縮時(shí)其內(nèi)部微觀裂紋的擴(kuò)展槼律進(jìn)行了研究。
