The complete elimination of flaws in complex parts raises the overall costs, especially under stringent safety or service targets, while advanced knowledge might grade the risk of running defected parts with savings.

Introducing the novel concept of defect tolerance, this work proposes to exploit experiment-based full-field measurements from optical techniques, in conjunction with fatigue spectral methods and dynamic excitation signatures, for the definition of a macro-scale defect risk index mapping, retaining the most advanced knowledge available about task-related loading, cumulated damage and inherent structural dynamics of a real object in assembling conditions. The acceptance threshold on the risk index map can discriminate among dangerous permutations of defect locations. Meaningful examples are given on an aluminium thin plate, as a lightweight structure with complex structural dynamics.

完全消除复杂零件中的缺陷会提高总体成本，尤其是在严格的安全或服务目标下，而先进的知识可能会降低运行缺陷零件的风险并节省成本。

引入缺陷容限的新概念，这项工作建议利用光学技术的基于实验的全场测量，结合疲劳光谱方法和动态激发特征，来定义宏观缺陷风险指数映射，保留最先进的知识可用于与任务相关的负载、累积损伤和真实物体在组装条件下的固有结构动力学。风险指数图上的接受阈值可以区分缺陷位置的危险排列。在铝薄板上给出了有意义的例子，作为具有复杂结构动力学的轻质结构。
