Computational Biomechanics and its Applications in Injury Prediction and Prevention

Computational biomechanics uses computer modeling and simulation methods to understand the complex biomechanical behaviors of normal and pathological bio-tissues.  This presentation will cover several aspects of computational biomechanics, including anthropometric and anatomical modeling, simulations of musculoskeletal motions, and modeling of tissue biomechanics. Different computational methods of biomechanical simulations, including multibody dynamics, finite element method (FEM), computational fluid dynamics (CFD), and fluid-structure interaction (FSI), will be introduced along with their various applications such as human body dynamics, active soft tissue biomechanics, cardiovascular blood flow, and respiratory air flow for drug delivery. The applications of computational biomechanics in injury prediction, protection, and performance augmentation will be presented with a few examples. First, the creation of personalized biomechanical models for injury prediction and prevention will be emphasized. Second, human musculoskeletal simulations will be used to evaluate musculoskeletal loading and injury under heavy load carriage or extreme conditions and to evaluate performance augmentation from exoskeleton designs and control. Last but not the least, high fidelity computational modeling of multiphysics problems will be demonstrated on blast induced traumatic brain injury (TBI), ballistic injury, etc.
