FEA & simulation basics

Validate before you cut metal.

Analysis

Overview

Finite Element Analysis (FEA) simulates stress, deflection, and thermal behavior by discretizing a part into elements. It validates that a design survives its loads before a physical prototype is built.

Step by step, with examples

  1. 1

    Geometry

    • Simplify and defeature the CAD.
  2. 2

    Discretize

    • Split into finite elements.
  3. 3

    BC+forces

    • Apply constraints and loads.
  4. 4

    Stress

    • Check vs yield and convergence.
    • Example: FoS > 1

Overview

Finite-element analysis estimates stress/deflection under loads; quality depends on mesh, boundary conditions, and material model.

Common pitfalls

  • Garbage boundary conditions
  • Singularities at sharp corners
  • Trusting results without a sanity check
