The main objective of this project is to develop a computational 2D/3D FEM model accounting for the visco-elastic behaviour of a polymer coating within the roll to roll embossing process used to product market leading organic coated steel at Tata Steel's Shotton works on Deeside. As well as the complex thermal-mechanical contact conditions, mold pattern and loading/filling and recovery stage post contact/embossing will be included. This novel model will have to account for complex multi body contact within the mathematical representation of the embossed texture pattern as well as the detailed property of the polymer under a range stress, temperature, strain rate and initial surface state.

该项目的主要目标是开发一个计算的2D/3D有限元模型，该模型解释了塔塔钢铁公司迪赛德的肖顿工厂在生产市场领先的有机涂层钢的辊对辊压花工艺中聚合物涂层的粘弹性行为。除了复杂的热机械接触条件外，还将包括模具图案和接触/压花后的加载/填充和恢复阶段。这种新的模型将不得不考虑复杂的多体接触内的压花纹理图案的数学表示，以及在一个范围内的应力，温度，应变速率和初始表面状态下的聚合物的详细属性。
