Corrosion-sensitive Multiscale Fatigue Modelling Cranfield University

Overview

This Corrosion-sensitive Multiscale Fatigue Modelling programme offered by Cranfield University investigates the degradation of metallic materials under corrosion-fatigue conditions. The research addresses the interaction between repetitive loading and environmental effects, examining how corrosion influences fatigue damage and contributes to component failure. The project aims to reduce uncertainties associated with conventional fatigue prognosis methods by developing physics-based approaches that explicitly account for environmental factors.

Key Facts

The research combines multiscale modelling with mesoscale experimental testing to study composition changes caused by corrosion and their influence on fatigue behaviour. Activities include the use of 3-D crystal plasticity models, evaluation of constitutive responses in corrosion-degraded specimens, and integration of computational and experimental results. The project is conducted within the Through-life Engineering Services (TES) Centre, providing access to expertise in condition monitoring, damage tolerance, asset management, and industrial collaborations.
