![]() ![]() Service lifetimes are predicted by means of degradation rate models, superposition principles, and parametrisation techniques. Accelerated testing methods for predicting static, creep, and fatig ue lifetime of various polymers and polymer composites under environmental factors’ single or coupled influence are overviewed. This review offers a systematised overview of the state-of-the-art models and accelerated testing methodologies for predicting the long-term mechanical performance of polymers and polymer composites. Based on physical observations of composite macroproperties, engineering and phenomenological models provide manageable representations of complex mechanistic models. Durability prediction models are often subject to conflicting requirements of versatility and minimum experimental efforts required for their validation. Therefore, modelling is an affordable alternative that can partly replace extensive testing and thus reduce validation costs. Validation of new composite materials and structures often involves lengthy and expensive testing programs. ![]() The uncertainty of the material interaction with the environment compromises their superior strength and stiffness. Polymers and polymer composites are negatively impacted by environmental ageing, reducing their service lifetimes. ![]()
