常見(jiàn)例句雙語(yǔ)例句The formula of the fatigue crack propagation rate was directly derived from the fatigue damage criterion.通過(guò)疲勞損傷準(zhǔn)則，導(dǎo)出疲勞裂紋穩(wěn)定擴(kuò)展速率的計(jì)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(shuō)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(kuò)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(kuò)展的能量釋放率理論對(duì)脆性材料受軸向壓縮時(shí)其內(nèi)部微觀裂紋的擴(kuò)展規(guī)律進(jìn)行了研究。 返回 crack propagation criterion
