By shifting the mean stress and the sine wave stress amplitude, uniaxial cyclic experiments were performed to study the dynamic response of fluid-saturated sandstones and marbles.
在单轴循环加载实验中不断改变平均应力和正弦波应力振幅的实验条件下，研究饱和砂岩和大理岩的动态响应。
The component randomness is considered. The SFEM is introduced in the iterative formulas of EFEM under cyclic loading to obtain the random response of local stress and strain.
考虑零构件的随机因素，将随机有限元方法引入到交变载荷下弹塑性有限元的迭代格式中，得到局部应力应变的随机响应，为低周疲劳可靠性分析提供了更精确的依据。
The modified rainflow counting method can take out all the full cycles truly existing in the real stress-strain response, so it is a more reasonable cyclic counting method than the traditiona…
