Laser Engineered Net Shaping (LENSᴜ) is an advanced rapid manufacturing technique that encompasses intricate thermal, mechanical, and metallurgical interactions. The Finite Element Method (FEM) offers a highly accurate framework for simulating this process, thereby enabling the optimized selection of process input parameters and facilitating the production of components with enhanced thermo-mechanical characteristics. In the present investigation, the commercially available FEM software ANSYS is employed to predict transient thermal histories, total structural deformation, von Mises stress distributions, and shear stress fields generated within a thin-walled structure and its supporting substrate, both fabricated from AISI 304 stainless steel. The numerically obtained results are subsequently validated against experimentally measured data to establish the reliability and accuracy of the proposed computational framework.
