FEA: Breaking the Part Before You Build It

Definition

Finite Element Analysis (FEA)

A computerised simulation method that breaks down a model into small elements to analyse how it responds to physical forces.

Breaks a part into small elements (a “mesh”)
Applies loads or conditions (e.g. weight, wind)
Calculates the response of each element
Displays results using colour-coded stress maps or deformation visuals

Why Simulate Instead of Test

Identifies weak points in a design
Helps test different materials and shapes
Reduces the number of physical prototypes needed
Supports safer, lighter, more efficient products

Key Outputs of FEA

1 - Stress Analysis: Identifies areas of high stress that may lead to failure.

2 - Displacement: Shows how much a part will deform under load.
