The Banff International Research Station will host the "Mathematical Constitutive Models and Numerical Methods to Simulate Soft Tissue Under Impact Loading" workshop in Banff from April 8, 2022, to April 10, 2022.

Over the last decade, computational human body models have become prolific in both academic studies and industrial design with the aim to improve human safety in impact events, ultimately to address ‘the experiment that cannot be undertaken’. That is, injurious tests on a live human cannot be undertaken, although this knowledge is critical to reduce injury risk in everyday exposures including automotive crash scenarios and sports impacts. More recently human models are critical to simulate response to automated braking and crash avoidance systems, as well as for the development of safety systems in autonomous vehicles, which cannot be addressed using traditional methods such as crash test dummies owing to the unconventional seating positions proposed.

The primary inputs to a detailed human model include geometry, boundary conditions and material properties. Material properties and constitutive models to implement these properties are widely regarded as one of the greatest challenges for the adoption and use of human models. This workshop will bring together world experts in tissue characterization, constitutive modeling and human body modeling to address an urgent need to improve mathematical constitutive models representing tissues in human models. This need is driven by the original intent for these models to predict Crash Induced Injuries in automotive crash scenarios, and the current urgent need to address new seating positions in autonomous vehicles, and human pre-crash response for automated driver assist systems such as automatic braking.

The Banff International Research Station for Mathematical Innovation and Discovery (BIRS) is a collaborative Canada-US-Mexico venture that provides an environment for creative interaction as well as the exchange of ideas, knowledge, and methods within the Mathematical Sciences, with related disciplines and with industry. The research station is located at The Banff Centre in Alberta and is supported by Canada's Natural Science and Engineering Research Council (NSERC), the U.S. National Science Foundation (NSF), Alberta's Advanced Education and Technology, and Mexico's Consejo Nacional de Ciencia y Tecnología (CONACYT).
