Helmet Impact Multiscale Modeling and Simulation

Developing safer bicycle and motorcycle bike helmets at reduced cost would greatly increase their effectiveness and usage, thus avoiding trauma, physical injuries or loss of life. With over 1 million road traffic deaths worldwide recorded annually between 2000-2016, out of which 54% represent cyclists, motorcyclists and pedestrians, the World Health Organization estimates that "head injuries are the leading cause of death and major trauma", and that "helmet use can lead to a 42% reduction in the risk of fatal injuries and a 69% reduction in the risk of head injuries" .These statistics highlight the importance and the existence of a great need and huge market potential for more effective and less expensive helmets. However, innovation is currently limited by the lack of accurate simulation methods, which entails lengthy testing and high development costs. Since no well-defined modeling methods exist at present, LX Sim, an engineering company in Quebec specialized in simulation and optimization of product design seeks research collaboration with Concordia University to develop modeling capabilities for simulating helmet impacts. Development of efficient and accurate modeling and simulation techniques for helmet design would allow for an increased number of design iterations before manufacturing of prototypes, which would greatly boost innovation and provide optimum design solutions for helmet manufactures in Canada. Improved helmet design will lead to significant reduction in head injuries and associated health costs.
