Abstract A pragmatic design strategy to achieve unusual mechanical responses in metal lattice structures is deployed. This strategy, referred to as behavior by design, is illustrated with an architectured material fabricated to provide a “whistle-blower” mechanical response under tensile loading. Struts with unusual geometries, e.g. dog-bone struts and corrugated struts, are assembled in parallel in a standard lattice unit-cell to obtain the targeted elasto-plastic behavior, here a “whistle-blower” behaviour. The design strategy benefits from the freedom provided by additive manufacturing.

增材制造使设计行为成为可能：举报人机械反应的案例

摘要 部署了一种实用的设计策略，以在金属晶格结构中实现不寻常的机械响应。这种策略被称为设计行为，用一种结构材料来说明，该材料制造用于在拉伸载荷下提供“告密者”机械响应。具有不寻常几何形状的支柱，例如狗骨支柱和波纹支柱，在标准晶格单元中并行组装以获得目标弹塑性行为，这里是“告密者”行为。设计策略受益于增材制造提供的自由度。
