| Abstract Scope |
In ductile metals, the strain or stress a material component can withstand before failure depends on the local stress state and size of any existing internal defects. As additively manufacturing is aimed at producing complex-shaped components with complex stress states, and the fabrication process itself can introduce lack-of-fusion and other internal defects, the combined impact of stress state and internal defects on the load carrying capacity of additively manufactured components must be understood for their use. This talk will discuss our methods for experimentally identifying and computationally modeling the combined impacts of stress state and defect size on the ductile failure of metals. The importance of considering these contributions to predict ductile fracture will be demonstrated in a complex shaped component and contrasted with conventional methods for defining failure. |
