The goal of the proposed research is to investigate the interaction between obese occupants and safety devices in a motor vehicle in the event of a motor vehicle crash. Specifically, we plan to measure the variation in acceleration and deflection of the head, neck, chest, and legs. These measurements will provide an overall level of risk for the occupant. To minimize costs and maximize the capacity for recording measurements, a robust computer model will be developed to assist in this project. In particular, LS-DYNA, a non-linear, explicit, finite-element code, will be used. I have used this numerical tool throughout my graduate career at the University of Nebraska-Lincoln and have continued to use it as a research engineer at the University of Alabama at Birmingham. I have used it exclusively in modeling impact events, such as a car crash, where stress wave propagation and interaction add a layer of complexity to the process not experienced in low loading rates. This experience will allow me to create models with a high degree of accuracy and reliability. Additionally, the results of the model must be calibrated against physical tests. I have experience in comparing virtual data to physical data by comparing accelerations, displacements, and energies in the model to the corresponding parameter in the physical test results. One other key component to this project is in accurately representing the various materials that make up a human body in the LS-DYNA code. When a force is applied to a material, it will deform according to that material’s constitutive relationship. Material modeling begins with a single, small element and progresses to more complex shapes before ultimately being implemented in the final model. My dissertation dealt entirely with characterizing steel, wherein the primary interest was in the fracture of the material. Fracture represents the most extreme end of a spectrum of the material’s behavior. My experience dealing with this extremity qualifies me to conduct material characterizations for this project, which in turn will yield an accurate and reliable computer model, capable of measuring the level of risk associated with varying safety components in a vehicle’s cabin when an obese occupant is present.
