In the last decade, Additive Manufacturing (AM) technologies have been considered by both the automotive and aerospace industries for the production of end-use metallic parts, with a main focus on Powder Bed Fusion – Laser Beam / metallic (PBF-LB/M) technologies. However, AM parts present features that are deleterious to their cyclic properties. For a reliable design in terms of fatigue strength, existing influencing variables must be identified and transferred to a numerical model. In particular, different types of defects, as well as their distribution, should be taken into account. In addition to the identification of relevant parameters based on literature data, an AlSi10Mg component-like structure is assessed based on results from notched specimens and a linear-elastic assessment concept using effective stresses.

在过去十年中，汽车和航空航天工业一直在考虑使用增材制造 (AM) 技术来生产最终用途的金属零件，主要侧重于粉末床融合 - 激光束/金属 (PBF-LB/M ) 技术。然而，AM 部件存在对其循环特性有害的特征。对于疲劳强度方面的可靠设计，必须识别现有的影响变量并将其转换为数值模型。特别是，应考虑不同类型的缺陷及其分布。除了根据文献数据确定相关参数外，还根据缺口试样的结果和使用有效应力的线弹性评估概念评估了类似 AlSi10Mg 组件的结构。
