SUMMARY

The discussion focuses on the equilibrium equations of a rigid body in contact with an elastic deformable body. Key points include the application of a force \( F \) at an angle \( \beta \) on the rigid body, leading to deformation in the elastic body. The equilibrium conditions are expressed in terms of stress \( \sigma \) and the distance \( d \) from the forces causing moments. The conversation emphasizes the complexity of solving these equations analytically and suggests using Finite Element Analysis (FEA) software for numerical solutions, particularly when dealing with 2D problems.

PREREQUISITES
  • Understanding of equilibrium equations in mechanics
  • Familiarity with beam theory and stress analysis
  • Knowledge of Finite Element Analysis (FEA) principles
  • Basic proficiency in LaTeX for mathematical expressions
NEXT STEPS
  • Study the application of beam equations in elastic deformation scenarios
  • Learn about Finite Element Analysis (FEM) software, such as ANSYS or Abaqus
  • Research the relationship between forces and displacements in elasticity
  • Explore LaTeX documentation to improve mathematical expression formatting
USEFUL FOR

Mechanical engineers, structural analysts, and students studying elasticity and mechanics of materials will benefit from this discussion, particularly those interested in numerical methods for solving complex equilibrium problems.

Do I also perform inner product of stress with the normal vector of the surface when I integrate the stress over the area?
Of course

If I name the area as ##\Gamma_c## then it could be written this way ?
