Fatigue life prediction of injection moulded short glass fiber reinforced plastics

This work presents a framework that combines experimental and numerical efforts to accurately predict the fatigue life of short fiber reinforced parts. The framework combines engineering tools that allow design engineers to predict fatigue life of engineering plastics applications, including anisotropy in high detail. It includes characterization of the proper failure mechanisms, modelling anisotropy, and compensation for local stress concentrations. While step-by-step highlighting the key features and assumptions of the framework, the consistency and accuracy that can be achieved is shown. Subsequently the framework is validated on a representative demonstration part. (c) 2019 The Authors. Published by Elsevier B.V. Peer-review under responsibility of the Fatigue Design 2019 Organizers.
