With the freedom to create the material as components are built layer by layer, AM has permitted precise spatial control of the material properties in manufactured parts. In this work, an original approach is proposed to locally control component and process design and create intentionally weakened regions with designed fracture, which paves the way to tuneable mechanical properties. Tensile tests of specimens with embedded weakened area of various geometries are used to verify the feasibility of a-priori-designed fracture modes and to characterise the variation in material behaviour. The results show that an ad hoc design of the artificially weakened areas is effective for predictable breakage, with load and strain being the precursor for active control of the mechanical behaviour. 2023-08-25T07:26:25Z 2023-08-25T07:26:25Z 2023 Book https://link.springer.com/article/10.1007/s12540-023-01506-7 https://dlib.phenikaa-uni.edu.vn/handle/PNK/8953 en application/pdf Springer
