ICAM Webinar: Microscale Strain Accumulation as a Damage Driver in Metals

Microscale Strain Accumulation as a Damage Driver in Metals: Experiments and Machine Learning-based Modelling Recorded as part of a hybrid seminar co-hosted by the International Centre for Advanced Materials (ICAM) and the Henry Royce Institute, this presentation by Professor John Lambros explores how microscale strain accumulation influences damage and failure in metallic materials. Professor Lambros is Donald B. Willett Professor of Engineering in the Department of Aerospace Engineering at the University of Illinois Urbana-Champaign and a Distinguished International Associate of the Royal Academy of Engineering. Professor Lambros examines how the complex microstructure of polycrystalline metals creates localised strain variations during deformation and how these variations can contribute to material degradation over time. He discusses experimental approaches for measuring strain at the microscale using high-resolution digital image correlation (HR-DIC), with examples drawn from traditionally manufactured and additively manufactured metals. Professor Lambros also highlights how machine learning and crystal plasticity finite element simulations can be used to predict microstructural strain behaviour. By combining advanced experimental methods with data-driven modelling, the research provides insights into deformation, fatigue, creep, and failure mechanisms in engineering materials. The session was moderated by Professor Phil Withers, Regius Professor of Materials at the Henry Royce Institute and Professor of Materials at The University of Manchester. This recording will be of interest to researchers, students and professionals working in materials science, materials engineering, mechanics, manufacturing, structural integrity, fatigue, fracture mechanics, additive manufacturing and computational modelling.
