plane failure meaning in English
平面破坏
Examples
- 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。 - The paper presents a detailed numerical analysis to elucidate the failure pattern of the pit wall , the mechanism of the soil - nailed supporting system and its spatial behavior . firstly , a typical two - layer sand - cobble deposit was chosen for a detailed 2d - fem study . it was shown that due to the distinct behaviors of the upper soft sand layer against the much stiffer lower cobble layer , a bi - linear plane failure was recommended to be used in the limit equilibrium analysis
