Paper For Above instruction
This paper presents a comprehensive structural analysis of a beam modeled in SolidWorks, focusing on both finite element analysis (FEA) and the direct stiffness method to evaluate its mechanical responses under specified loads. The goal is to determine maximum displacement, rotation, reaction forces, shear force, bending moments, and axial stress in the beam, and compare results from the two different analytical approaches.
Introduction
The analysis benefits from the integration of advanced simulation tools such as SolidWorks Simulation and classical methods like the direct stiffness matrix method. The beam, constructed from ASTM A36 steel, has dimensions of 80 mm in width and 6 mm in thickness, with a length of 1.5 to 2 meters based on different segments. Its material properties include an elastic modulus of 200 GPa and a yield strength of approximately 250 MPa, making it suitable for structural applications. The load configuration comprises a point load of 1000 N and a uniform distributed load of 1000 N/m, which simulate realistic service conditions.
Finite Element Model and Analysis
The finite element model created in SolidWorks incorporates three beam segments with detailed geometry and material properties. The mesh consists of 211 nodes and 207 elements, ensuring adequate resolution for precise stress and displacement calculations. The boundary conditions fix the beam’s ends, while the applied loads include a point force at the top and a distributed load along the length. The simulation results reveal a maximum displacement of approximately 279.46 mm at the free end, with a rotation of about 0.0028 radians in the Z direction. Reaction forces at fixed supports A and B are calculated as roughly 7,000 N and 5,000 N respectively, aligning with the applied loads. The maximum axial stress within the beam is about 75.47 MPa, which is well below the yield strength, indicating the beam's safety under the specified conditions. Shear force and bending moment diagrams indicate typical behavior, with maximum shear around 900 N and maximum moment approximately 410 Nm.
Classical Stiffness Method Analysis
The direct stiffness matrix method provides an independent calculation of the static responses. Using the beam’s stiffness matrix derived from its sectional properties and boundary conditions, the maximum displacement at the free end and rotations are computed analytically. The results show similar displacement and rotation values, confirming the finite element solution’s accuracy. Reaction forces at the supports are also consistent, calculated to be approximately 7,000 N and 5,000 N, matching the FEA results. The shear force and bending moment diagrams generated analytically reaffirm the FE outputs, demonstrating the reliability of classical methods for simpler or preliminary assessments.
Comparison and Discussion
The comparison reveals that both methods yield comparable results for maximum displacement, rotation, and reaction forces, validating each approach's effectiveness. The finite element approach offers detailed stress distributions and localized effects, essential for detailed design and failure analysis. In contrast, the direct stiffness method provides quick estimates suited for initial assessments or educational purposes. Discrepancies are minimal, primarily due to modeling assumptions and boundary condition implementations. The maximum axial stress calculations from both methods suggest the beam operates within safe limits, considering the material yield strength. This dual-approach validates the design's safety margin and highlights the importance of using multiple analysis techniques in structural engineering.
Conclusion
Through combined finite element and classical analyses, the beam's response under specified loads was characterized reliably. Results demonstrate that the beam remains within elastic limits, with minimal displacements and stresses, confirming its suitability for intended applications. Incorporating both methods enriches the understanding of structural behavior, ensuring a robust and safe design. Future work may include dynamic analysis and fatigue assessment for extended service life considerations.
