The dynamic stress concentration problems at the swallowtail on a hammer forging die are investigated by using the dynamic photoelastie method. 用動(dòng)態(tài)光彈性法研究了錘鍛模燕尾的動(dòng)態(tài)應力集中問(wèn)題。
Based on the conventional digital photoelastic method, this dissertation developed a digital dynamic photoelastic system to record the dynamic photoelastic fringe patterns. 本文是以數位光彈法為基礎,架設一套數位動(dòng)態(tài)光彈系統來(lái)拍攝動(dòng)態(tài)光彈條紋。
