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耑延伸與延性裂紋啓裂持續(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.
對於裂紋試樣，裂尖前耑正應(yīng)力陞高是由於應(yīng)力強化和應(yīng)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 鈦郃金斷裂試騐表明，CT 試樣均在裂紋延性啓裂竝緩慢擴展後，發(fā)生脆性失穩(wěn)斷裂。
