这篇文章考察了两个相互交织的关于有缺陷的建筑材料的话题--它们的力学和优化设计。我们首先讨论控制缺陷敏感性的主要因素以及缺陷表征的一系列策略。强调了设计缺陷和制造缺陷对其宏观响应的影响，并强调了由添加剂制造技术引起的缺陷。作为缺陷敏感性的自然延伸，我们描述了建筑材料的设计方法，特别是拓扑优化的系统化工具。讨论了最近在优化公式中正式结合缺陷的扩展，其中的最终目标是生成容错的体系结构，并且在存在缺陷的情况下稳健地执行。最后，我们对该领域进行了展望，强调了未来研究的潜在领域。
This article examines two intertwined topics on architected materials with imperfections—their mechanics and optimum design. We first discuss the main factors that control defect sensitivity along with a range of strategies for defect characterization. The potency of both as-designed and as-manufactured defects on their macroscopic response is highlighted with an emphasis on those caused by additive manufacturing technology. As a natural extension of defect sensitivity, we describe the design approaches for architected materials with particular focus on systematic tools of topology optimization. Recent extensions to formally incorporate imperfections in the optimization formulation are discussed, where the ultimate goal is to generate architectures that are flaw-tolerant and perform robustly in the presence of imperfections. We conclude with an outlook on the field, highlighting potential areas of future research.
