⚙ Description:
Talk about changing SSS (Stress-Strain State)
Video discusses the impact of having different materials for various parts of a construction and how it influences stress, strain, and deformation. Two constructions are considered, each having a combination of materials (aluminum alloy and steel) for different parts. The key points covered include:

Construction Setup:
Two constructions with similar geometry, boundary conditions, and linear contacts (bonded) are analyzed.
Construction 1: Crank made from aluminum alloy, and the base and bolts made from steel.
Construction 2: Base made from aluminum alloy, and the crank and bolts made from steel.
Deformation Comparison:
Maximum deformation values are almost the same for both constructions but exhibit different distribution patterns.
Stress Comparison:
Stress distribution varies significantly between the constructions.
For the aluminum base construction, the crank is almost rigid, transferring most deformation to the base.
Stress differences are observed, with variations in maximum stress values and distribution patterns.
Linear vs. Non-linear Analysis:
Linear contacts result in about a 20% difference in deformation between the two constructions.
Non-linear contacts, specifically frictional contacts, further amplify stress differences, reaching approximately 17%.
Importance of Material Combinations:
Emphasis on the need to carefully consider material combinations for different parts of a construction.
Different materials with varying stiffness affect stress distribution and accuracy of results.
Recommendation:
Advise to explore various material combinations, check stress and deformation distributions, and not solely rely on overall construction results.
Viewer Engagement:
Encouragement for viewers to share comments and thoughts on the presented topic.
Key Takeaways:
Material combinations for different parts of a construction significantly impact stress, strain, and deformation distributions.
Even with the same geometry and boundary conditions, using different materials results in varying stress patterns.
Linear and non-linear analyses reveal differences in deformation and stress distributions between constructions.

Conclusion: This video provides valuable insights into the complexities of analyzing constructions made from different materials for various parts. Video demonstrates how material combinations can lead to distinct stress and deformation distributions, highlighting the importance of careful consideration in engineering simulations. The recommendation to explore and check various material combinations fosters a thorough understanding of the impact on accuracy and reliability in structural analyses.
