常見例句雙語例句The formula of the fatigue crack propagation rate was directly derived from the fatigue damage criterion.通過疲勞損傷準(zhǔn)則,導(dǎo)出疲勞裂紋穩(wěn)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.為了說明該準(zhǔn)則的應(yīng)用,文中具體研究了埋藏橢圓盤狀裂紋和直前緣穿透裂紋的擴展行為。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.本文利用混合型裂紋擴展的能量釋放率理論對脆性材料受軸向壓縮時其內(nèi)部微觀裂紋的擴展規(guī)律進行了研究。 返回 crack propagation criterion
