高强钢超高周疲劳裂纹萌生和初始扩展的机理与模型

open access: yes, 2012
超高周疲劳是指10~7及以上周次的疲劳损伤和断裂。对于高强钢的超高周疲劳,裂纹萌生与初始扩展阶段占据整个疲劳寿命的绝大部分。超高周疲劳的裂纹损伤往往起源于材料内部,裂纹源呈现"鱼眼"和"细晶区"特征 ...

高温后结构钢材单调拉伸和循环荷载试验研究

open access: yesJianzhu Gangjiegou Jinzhan
现有的火灾后钢材残余特性研究大多着眼于钢材在高热下或升温后的残余静力特性,而对过火后钢材在循环荷载作用下的滞回和抗震特性鲜有研究。对于建筑结构和桥梁中常用的Q235和Q355两种钢材,对其进行了500~1 000 ℃的模拟火灾加热处理,并进行自然冷却或浸水冷却。对于冷却后的钢材试样进行了单向拉伸试验和2种不同荷载变化规律下的循环加载试验,得到了模拟温度和不同降温方式对于两种钢材滞回特征的影响规律。由试验结果可得,在受到的最高温度不高于600 ℃时 ...
