Michael Wisnom, has a BSc in Mechanical Engineering from Imperial College, and a PhD from Bristol University. He worked on a wide range of projects including structural analysis of the Piaggio Avanti airframe. He joined the university of Bristol as a lecturer in aircraft structures in 1987, was appointed as Professor of Aerospace Structures in 1995 and established the Advanced Composites Centre for Innovation and Science in 2006. He is a leading expert on the mechanics of fibre reinforced composites, failure mechanisms and finite element analysis, with over 350 published papers. He is Director of the Rolls-Royce Composites University Technology Centre, a member of the steering board of the National Composites Centre and Editor in Chief and European Editor for Applied Science and Manufacturing of the international journal Composites Part A.

报告摘要

Finite element analysis can be used to predict the strength of a full-size aerospace stiffened panel with a large notch provided the process zone is taken into account and appropriate fracture toughness data is used. The reasons for the large variation of reported values of translaminar fracture toughness are considered, both for initiation and propagation. The effects of ply thickness, layup, the development of the fracture process zone and the implications for predicting response of notched structures are discussed.
