Structural analysis of truss in Nastran/Patran

I performed a structural analysis of a truss/rod structure using MSC Patran and Nastran, focusing on evaluating the stress distribution, internal forces, and deformation behavior under static loading conditions. The structure was modeled as a bar/rod element system, representing a simplified framework commonly used in structural engineering applications. The analysis process began with creating the geometric model of the truss structure, followed by defining material properties, element types, and cross-sectional parameters for each structural member. The structure was then discretized using finite element bar elements, which are suitable for analyzing axial forces and deformation in slender members. Appropriate boundary conditions and constraints were applied to simulate real-world support conditions, while external loads were introduced to evaluate the structural response. The simulation was performed under a static subcase, allowing the calculation of bar forces, translational displacements, rotational deformation, and stress distribution within the structure. The results were visualized using fringe plots, which clearly illustrate the von Mises stress distribution, bar force magnitude, and deformation patterns across the structure. The analysis identified regions experiencing maximum stress concentration and displacement, which are critical for evaluating structural integrity and potential design improvements. This project demonstrates practical experience in Finite Element Analysis (FEA), structural simulation, load application, boundary condition definition, and post-processing of results using MSC Patran/Nastran.
