This article focuses on the problem of maximal compliance design of a hyper‐elastic solid with the optimal design of human skin grafts as the application in mind. The solution method is a phasefield‐based topology optimization method that supposes multiple local phasefields and a minimum distance constraint in order to prevent the phasefields from merging. Consequently, structurally disintegrating solutions such as by the coalescence of voids can be prevented. The method is used to find an optimal graft meshing pattern for a sample that is subjected to a biaxial extension of up to 150%, which corresponds to an expansion ratio of 1 : 2.25. Three prospective unitcell solutions that exhibit meta‐material behavior are proposed for a periodic graft pattern. The results are a step toward improving the skin graft meshing efficiency. This work does not cover experimental validation.

使用基于相场的拓扑优化实现最大顺应性的最佳结构模式：用于提高皮肤移植物啮合效率的应用

本文重点讨论超弹性实体的最大顺应性设计问题，并以人体皮肤移植物的优化设计为应用。该求解方法是一种基于相场的拓扑优化方法，它假设多个局部相场和一个最小距离约束，以防止相场合并。因此，可以防止结构分解溶液，例如由于空隙的聚结。该方法用于为经受高达150%的双轴延伸（对应于1 : 2.25的膨胀比）的样品寻找最佳接枝啮合模式. 提出了三种具有超材料行为的前瞻性晶胞解决方案用于周期性移植图案。结果是朝着提高皮肤移植物啮合效率迈出的一步。这项工作不包括实验验证。
