钢热应力疲劳探讨 - In this research , fatigue life of laminate composite is predicted phenomenologically , dealing mainly with in - plane stresses without accounting for out - of - plane failures such as delamination . fatigue modulus is used as a physical parameter which helps to describe the basic fatigue behaviour of unidirectional laminates and obtain expressions for cumulative damages defined by strains . based on some typical fatigue test data for unidirectional composite laminates , a cumulative fatigue damage model is presented for predicting the fatigue life of multidirectional laminates with arbitrary stacking sequence under complicated fatigue loadings
本文以碳纤维/树脂基t300 / qy8911层压结构为研究对象，从唯象的观点出发，以疲劳模量为参量构造损伤函数，基于几组最典型的单向板疲劳试验数据，建立单向板在多轴循环应力作用下的疲劳寿命模型，并以此为基础，发展同种材料体系的任意铺层形式的多向层压板在复杂循环载荷作用下的疲劳寿命预测方法。 - An experimental program which includes lots of unidirectional laminae is conducted using t300 / bmp - 316 material for researching the static and fatigue behaviour of the unidirectional ply . the experimental research for mechanical behaviour of a unidirectional lamina is to set up expressions of the normalized fatigue life , the residual strength degradation and the residual stiffness degradation of a unidirectional ply in the longitudinal , transverse and in - plane - shear directions , which also verifies the fact of nonlinear shear stress - strain behavior of a unidirectional ply in the 1 - 2 planes
其中:分别对材料t300 / bmp - 316单向层合板纵向、横向及面内剪切静载力学性能及疲劳特性进行了试验研究,并采用最小二乘法拟合得到各主方向正则化疲劳寿命表达式,以及单层板各主方向疲劳加载剩余刚度退化表达式及剩余强度退化表达式;试验同时验证了单向层合板1 - 2面上明显的剪切应力应变非线性关系。
