We will develop and calibrate a model of polyether polyurethane solid foams for the realistic computational simulation of occupant-seat interaction in automotive engineering. The project involves theoretical, experimental, and computational work at the forefront of research on materials governed by nonconvex potentials. This will be a cooperative effort with the Safety Research & Development Group at Ford Research Labs and the computationalmechanics group of Prof. Cuitino (Rutgers).We will perform measurements of displacement fields using a novel, finite element-based image correlation technique. A set of tests on rate effects and hysteresis will be performed at Ford. We will also undertake an unprecedented factor analysis of microstructural features. The results will serve to calibrate the computational model, which will be based on nonlinear, homogenized periodic cell structures.

我们将开发和校准聚醚聚氨酯固体泡沫模型，用于汽车工程中乘员-座椅相互作用的真实计算模拟。该项目涉及理论，实验和计算工作的前沿研究材料受非凸势。 这将是与福特研究实验室的安全研究开发小组和Cuitino教授（罗格斯大学）的计算力学小组的合作努力。我们将使用一种新的，基于有限元的图像相关技术进行位移场的测量。将在福特进行一系列速率效应和滞后试验。我们还将对微观结构特征进行前所未有的因素分析。 结果将用于校准的计算模型，这将是基于非线性，均匀化的周期性细胞结构。
