Career: Foam Models for Occupant-Seat Interaction Engineering

我们将开发和校准一个聚醚聚氨酯固体泡沫塑料模型，用于汽车工程中乘员-座椅相互作用的真实计算模拟。该项目涉及由非凸势能支配的材料研究的前沿的理论、实验和计算工作。这将是与福特研究实验室的安全研究和开发小组以及奎蒂诺(罗格斯)教授的计算力学小组的合作努力。我们将使用一种基于有限元的图像相关技术来测量位移场。福特将进行一系列关于速度效应和滞后的测试。我们还将对微观结构特征进行前所未有的因素分析。计算结果将用于校准计算模型，该模型将基于非线性、均一化的周期细胞结构。

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.
