ductile crack

基本解釋

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。
