The impact engineering group was founded by Professor Nelson Lam from the University of Melbourne in 2009 in collaboration with Professor Emad Gad from Swinburne University of Technology. It started off with some miniature laboratory scale tests and quickly expanded within 10 years time. A large-scale impact experiment was undertaken recently on a full-scale reinforced concrete wall in collaboration with Swinburne University of Technology, Australia in 2018.An ARC Discovery Project (2017-2020) titled: New Approach for Design of Barriers for Impact has been awarded to Professor Lam and Professor Gad in collaboration with Dr Mahdi Miri Disfani and Professor Tuan Ngo of the University of Melbourne. The aim of the impact engineering group is to develop simple solutions to sophisticated problems in a cost effective manner. As opposed to the conventionally adopted force-based approach to the structural design of a barrier. We focus on the use of displacement-based approach which has been proven to provide less conservative design. Our design philosophy is highly transparent based on fundamental principles of physics. There is no black box operation in the design process as we believe that the key to a good design is to understand and solve the problem from first principles. We cover a wide range of real world impact problems including rockfall impact, vehicular impact, impact on building facade and skylights in bad weather.
