Explain stress strain curve? What is FEM? What is steps in FEA?

Question

Accepted Answer

Stress-strain curve shows the relationship between stress and strain in a material. FEM is a numerical method to solve engineering problems. FEA involves pre-processing, solving, and post-processing.

Stress-strain curve is a graphical representation of the material's behavior under stress.
FEM is a numerical method that divides a complex problem into smaller, simpler parts to solve it.
FEA involves pre-processing (model creation), solving (applying loads and constraints), and post-processing (analyzing results).
Stress-strain curve helps in determining the material's strength, stiffness, and ductility.
FEM is used in various fields like structural analysis, fluid dynamics, and heat transfer.
FEA is used to analyze the behavior of structures under different loading conditions.
FEA software like ANSYS, Abaqus, and COMSOL are widely used in the industry.
