Analyses of dynamic crack propagation and crack arrest for a specified initial flaw size, external geometry, and applied load can be conducted in either of two different ways . 為特定的初始裂紋尺寸、外部幾何形狀和應(yīng)用載荷對(duì)動(dòng)態(tài)裂紋擴(kuò)展和裂停止進(jìn)行分析,可以用兩種不同方法中的任何一種來(lái)進(jìn)行。
Perhaps the simplest illustration of the role of stress waves in dynamic crack propagation and crack arrest is given by the one-dimensional analysis of the double torsion specimen . 也許最簡(jiǎn)單地說(shuō)明在動(dòng)態(tài)裂紋擴(kuò)展和止裂中應(yīng)力波的規(guī)律是由雙扭(DT)試件的一維分析給出的。
