我们提出了一种用于杂交金属泡沫的数值均质化方法，即被电载以改善其机械性能的泡沫。基于有限细胞法，得出了正在研究的杂交金属泡沫的微观结构的ACT扫描的空间离散化，并将窗口方法应用于计算有效的材料特性。我们证明，该方法提供了有效计算和研究杂交金属泡沫涂层厚度的影响的可能性。 （c）2015 Elsevier Ltd.保留所有权利。
We present a numerical homogenization approach for hybrid metal foams, i.e. foams that are electrocoated to improve their mechanical properties. Based on the finite cell method, a spatial discretization of a ACT-scan of the microstructure of the hybrid metal foam under investigation is derived and the window method is applied to compute effective material properties. We demonstrate that this method offers the possibility to efficiently compute and study the influence of the coating thickness of hybrid metal foams. (C) 2015 Elsevier Ltd. All rights reserved.
