Heat Source Modeling and Residual Stress Analysis for Metal Directed Energy Deposition Additive Manufacturing

- Highlights
• This study evaluating heat source model for single and multi-track deposition by using InssTek's DMT Technology
• The concentrated heat source does not require melt pool dimension measurement for thermal model simulation. Thus, it reduces the considerable time for preprocessing.
• A good agreement was noticed for the concentrated heat source model melt pool, with an experimentally determined melt pool, using an optical microscope.
