Based on the concept of Simo’s energy index, the energy index of loess load damage was put forward. And analyzed structure breakage and degradation of mechanic and strength index, the evolvement procedure of loess load damage was put forward.
其中,首次提出黄土的增湿损伤变量的定义及与含水量有关的增湿损伤等效能量指标,描述增湿损伤的演化过程;参照Simo提出的能量指标概念,定义黄土的加载损伤的能量指标,并通过黄土加载过程中的结构破损、力学和强度指标的劣化分析,确定黄土的加载损伤演化方程;结合以塑性功为硬化参数的椭圆形屈服面,根据相关联流动法则及损伤理论推导出了黄土弹塑性损伤本构模型。

In comparison, sandstone is more sensitive to the freeze - thaw cycles, and load damage will lead to the destruction of shale eventually.
相比而言,砂岩对冻融循环更敏感,而受荷损伤最终导致页岩破坏。
Beyond these benefits, speaker selectors also help to protect the amplifier from damage by reducing or balancing the load.
除了这些优点外,喇叭选择器通过减少或平衡负荷还有助于保护扩音器免受损害。
At first, small wave load have caused an amount of damage and decrease the ultimate bearing capability to the structures, then fatigue load have caused wholly destroy.
