IRAQI JOURNAL OF APPLIED PHYSICS Vol. 22, No. 3, July-September 2026, pp. 513-524 Numerical Analysis of Thermal Nabhan A. Hamdoon 1 Omar A. Mohammed 2 Strain Resistance of 6061 Ahmed M. Daabo 3* Tawfik Badawy 4 Aluminum Alloy under Various Plasma Source Parameters Recently, plasma sources have served an indispensable function across a wide range of applications, particularly in material fabrication and related thermal loading environments. This study investigates the thermomechanical response of 6061 Al alloy under different plasma heat flux conditions. A coupled thermal structural finite element model was developed and analyzed using ANSYS Workbench 2021 R1. The numerical results were validated against published experimental data and showed good agreement with a 4.4% deviation. Across the investigated plasma heat flux range (0.5 to 0.7 MW/m2), the simulations predict peak Von Mises stress up to about 5.9 MPa and peak normal stress up to about 2.6 MPa, with the highest stresses localiz
