我校从事下列研究工作: 1.疲劳损伤与断裂 对铝和Al—Cu单晶,从实验上获得了疲劳裂纹直扩展的条件,并证实滑移损伤对开裂起控制作用,而撕裂过程则起加速作用。 Our school is engaged in the following research work: 1. Fatigue damage and fracture For aluminum and Al-Cu single crystal, the condition of direct expansion of fatigue crack was experimentally obtained and it was confirmed that slip damage played a controlling role in cracking, while the tearing process Play acceleration.
