electropulsing was applied to an Al-Mg-Si alloy between solution and ageing process. XU et al [22] showed that electropulsing can remarkably refine the microstructure of hot-rolled 2024 aluminum through... the first 1 h of the creep ageing process; (2) sequentially heat using a furnace; (3) remove the creep-aged specimen from the furnace after ECA test, and then air cooled to room temperature......

设过程 Fig. 2 Embedding process of sensors 1.4 试验方案 粉土变形特性受含水率影响显著,在飞机荷载作用下容易产生不均匀变形.据此试验方案设计以累积注水量为单一变量对道基进行注水试验,以此模拟测试现场粉土湿化过程中,飞机荷载作用下道基变形特性. 依据民用机场道面设计规范[20],以大型飞机A380-800为例,单个机轮荷载为1.47 MPa,轮印面积为......
的不同部位表现出不同的破坏模式,在边坡前缘中下部主要表现为蠕滑破坏模式,而后缘中上部主要表现为剪切破坏模式,最终呈现出"牵引式"的破坏模式,如图7(c)所示. 图7 泥化夹层倾角为40°和厚度为10 mm时模型边坡动力失稳过程 Fig. 7 Dynamic instability process of model slope with 40° in dip angle and 10 mm......
