基本解釋[材料科學]延性破裂英漢例句雙語例句The crack growth process is a continuous process of alternating crack-tip stretching and ductile crack cracking.裂紋的增長過程是一個裂紋尖端延伸與延性裂紋啟裂持續(xù)地交替出現(xiàn)的過程。For precraked specimen , the elevation of normal stress ahead of the ductile crack is related to the stress intensification and the strain hardening.對于裂紋試樣，裂尖前端正應力升高是由于應力強化和應變強化這兩個因素決定的。Fracture test of the BT20 indicates that brittle unstable fracture occurs after ductile crack initiation and slow propagation for all the compact tension (CT) specimens.BT20 鈦合金斷裂試驗表明，CT 試樣均在裂紋延性啟裂并緩慢擴展后，發(fā)生脆性失穩(wěn)斷裂。ductile crack更多例句詞組短語短語ductile -crack-growth fracture 延性裂紋擴展斷裂ductile crack propagation 延性斷裂擴展;延性裂紋擴展damage ductile crack 延性裂紋擴展ductile crack initiation 韌性啟裂ductile crack extension 延性裂紋擴展ductile crack更多詞組專業(yè)釋義材料科學延性破裂
