Different Statement - Different FEA Result. How Boundury Conditions influence Simulations

With #Ansys #Workbench on example of cranck #FEA Simulation try to show difference in results, which depends on statements (Boundary conditions in this video) 👉Details in description👇 ⚙ Description: Summary: In this video, the presenter explores different types of boundary conditions and their impact on the behavior of a mechanical component, specifically a crank. The objective is to demonstrate how different boundary conditions can lead to varied results in terms of deformations and stresses. Here are the key points discussed: Default General Statement: Fully bonded connection for all parts. Default mesh for all parts. General linear material. Fully fixed boundary conditions on three faces. Results: Symmetrical deformations and stresses. Total deformation is about 570 microns, and stress is approximately 240 megapascals. Variant 1 - Suppressing One Fixation: Suppress fixation on one face. Results: Deformations increased to 590 microns, and stresses show some differences, particularly with higher stresses in certain regions. Variant 2 - Displacement Fixation: Fixation with displacement in y-direction only. Results: Deformations further increased to 655 microns. Stress distribution shows differences compared to previous variants. Variant 3 - Mixed Fixation: Displacement fixed in y-direction, and additional points fixed in different directions. Results: Deformations increased to 750 microns, stressing the importance of the chosen boundary conditions on deformation behavior. Variant 4 - Remote Displacement: Usage of remote displacements and additional fixed rotational degrees. Results: A more symmetrical model with deformations close to 770 microns. Stress distribution differs from previous variants. Variant 5 - Fully Symmetrical Model: Utilizing remote displacements and additional fixed rotational degrees for symmetry. Results: Achieves a more symmetrical deformation pattern with stress distribution differences compared to previous variants. Conclusion: Different boundary conditions lead to varied deformations and stress distributions. The choice of boundary conditions depends on the physical accuracy needed for a particular analysis. Emphasizes the need for understanding the specific requirements of the task to choose appropriate boundary conditions. Mention of scenarios where different boundary conditions might be suitable for specific analyses. Key Takeaways: Varying boundary conditions significantly impact deformations and stress distributions. Physical accuracy should guide the choice of boundary conditions. Deformation behavior depends on the specific task or component being analyzed. Symmetry can play a role in achieving more accurate results. Conclusion: The video provides insights into the influence of different boundary conditions on the behavior of mechanical components, emphasizing the importance of choosing appropriate conditions based on the specific analysis objectives. The demonstrations highlight the variations in deformations and stress distributions resulting from different statements, enriching the understanding of structural mechanics in engineering applications.
