Abstract

A phenomenological model describing fatigue damage accumulation by using a tensor measure of the accumulated damage caused by different cyclic stresses is presented for estimating numerically the fatigue life of carbon fibre-reinforced plastics operating under complex stress state conditions. A procedure for calculating the fatigue life by using the presented model is given. An example demonstrating acceptable agreement between experimental and calculated data is presented.

如何使用张量累积疲劳损伤量度分析复杂应力状态下碳纤维增强塑料的疲劳寿命

摘要

提出了一种现象模型，该模型通过使用张量测量由不同循环应力引起的累积损伤来描述疲劳损伤累积，以数值估算在复杂应力状态下工作的碳纤维增强塑料的疲劳寿命。给出了使用该模型计算疲劳寿命的程序。给出了一个示例，该示例说明了实验数据与计算数据之间的可接受的一致性。
