Finite Element Analysis (FEA)
Finite Element Analysis (FEA) is a computer-based technique that predicts how real-world objects and systems will react to forces, vibrations, heat, and other physical effects. By breaking a complex object into a mesh of smaller “finite elements,” engineers can test designs virtually, identify weaknesses, and make informed decisions before creating costly prototypes.
How FEA Works
- Discretization: Break the object into a mesh of elements (triangles, tetrahedrons, or hexahedrons).
- Mathematical Equations: Apply physical laws to each element to model behavior.
- Stiffness Matrix Formation: Combine equations into a stiffness matrix linking nodes.
- Computational Solution: Solve the matrix to predict response under applied conditions.
Benefits of FEA
