讲座题目：To develop a progressive damage model for thermoplastic composites
讲座摘要：Composite materials now dominate the structure of the latest wide-body twin-engine passenger aircraft and are making increasing inroads into smaller narrow-bodies. An efficient and reliable physical testing method was used to conduct the experimental validation, also to help understand the damage behaviour of composite laminates. A computational model, which accounts for both interlaminar and intralaminar damage in composite laminates, implemented as a user subroutine in Abaqus/Explicit, was developed. The load-displacement response, energy absorption and damage morphology obtained from the numerical simulation were compared with the results obtained from the physical tests. Subsequently, the application of the fully validated computational model is also discussed.
Dr Haibao Liu is a Research Associate at AVIC centre, Imperial College London. He obtained his PhD degree from Queen’s University Belfast, where he conducted research on ‘Modelling the behaviour of composite transportation structures under impact, compression-after-impact and crush loading’ sponsored by Bombardier Aerospace. He jointed Prof John Dear's group at Imperial in Mar 2018. He is currently working on the impact performance of thermoplastic composites, using both experimental and numerical methods.
