| Abstract Scope |
SLM is a promising manufacturing technique which has been developed significantly in recent years. Additive nature of the process enables manufacturing of complex geometries with minimum wastage. However, residual stress formation during building of SLM process has negative effects on mechanical properties and service life such as cracking or reducing fatigue life therefore strong understanding of residual stress is required in order to mitigate the detrimental effects. At this point numerical simulation techniques offer an applicable practice for the understanding, prediction and mitigation of residual stress problem. In this study, macro scale mechanical and thermomechanical simulations are practiced with Simufact Additive software for SLM processing. Experimental validations are practiced with contour method. Experimental and computational efforts yielded highly consistent results. The applicability of the Contour method in bulk SLM parts has been confirmed and the simufact additive software has been verified to give reliable results as a simulation tool. |
