Fatigue strength is closely related to the material, the structural arrangement, the manufacture technology as well as the levels of the stress and strain.
疲劳寿命与材料、结构形式、加工工艺以及应力应变水平有关。
Further the structural parameter is applied to analyze stress-strain behaviors; and a structural stress-strain relation is set up.
将该式引入结构性黄土应力应变特性分析，提出了考虑结构性参数的应力-应变关系。
However, global structural stress and strain distribution can be calculated quickly, correctly and intuitively by finite element software.
而用有限元软件进行计算能够快速、准确、直观地得到结构上各部位的应力、应变等参数的分布情况。
