Modelling the effect of temperature on the probabilistic stress–life fatigue diagram of glass fibre–polymer composites loaded in tension along the fibre direction

摘要: Predicting the fatigue performance of composites has proven to be a challenge both conceptually, due inherent complexity phenomenon, and practically, because resource-intensive process testing. Moreover, mechanical behaviour polymer matrix exhibits complicated temperature dependence, making prediction under different temperatures even more complex resource intensive. The objective this paper is provide method for life glass–polymer loaded in fibre direction at various with minimal experimental efforts. This achieved by using static strength degradation approach modelling, where only two parameters (including strength) are dependent, conjunction relationships these model dependence. relies on data single simple tests predict effects material’s behaviour. validated unidirectional one woven glass–epoxy found accurately effect composites. A obtain probabilistic stress-life (P−S−N)(P-S-N) diagrams including also presented.
