Abstract

This review explores uniaxial ultrasonic fatigue (USF) testing as a common and dependable method for quantifying the extended fatigue life of fiber-reinforced polymer (FRP) composites. The objective is to explain the complexities governing the fatigue life behavior of FRPs, particularly in the realm of very high cycle fatigue (VHCF) where the number of loading cycles exceeds 10⁷. To this end, this review encompasses the analysis of VHCF behavior, including the derivation and interpretation of stress–life (S–N) data, the evaluation of various fatigue damage mechanisms (i.e., controlling mechanisms of crack initiation and propagation) exhibited in FRP composites, and a thorough investigation of the frequency-dependent effects on fatigue responses. Furthermore, this review tries to analyze the microscopic intricacies intrinsic to the VHCF failure of FRP composites, encompassing aspects such as fiber-matrix de-bonding, matrix cracking, and delamination, unveiling their modes and effects in a detailed manner. This review also underscores the pivotal integration of simulations, machine learning, and modeling techniques, emphasizing their crucial role in explaining both macroscopic and microscopic interactions governing the VHCF of FRPs.

纤维增强聚合物复合材料的超高循环疲劳：单轴超声波疲劳

本综述探讨了单轴超声波疲劳（USF）测试作为量化纤维增强聚合物（FRP）复合材料延长疲劳寿命的常用可靠方法。其目的是解释 FRP 疲劳寿命行为的复杂性，特别是在加载循环次数超过 107 次的超高循环疲劳 (VHCF) 领域。为此，本综述涵盖了对 VHCF 行为的分析，包括应力寿命（S-N）数据的推导和解释、对玻璃钢复合材料中表现出的各种疲劳损伤机制（即裂纹萌发和扩展的控制机制）的评估，以及对频率对疲劳响应影响的深入研究。此外，本综述还试图分析玻璃纤维复合材料 VHCF 失效的微观内在复杂性，包括纤维-基体脱粘结、基体开裂和分层等方面，详细揭示其模式和影响。本综述还强调了模拟、机器学习和建模技术的重要整合，强调了它们在解释玻璃钢 VHCF 的宏观和微观相互作用方面的关键作用。
