Formula & Methodology Behind FEA Hand Calculations
The formula used for FEA hand calculations is based on Hooke’s Law and the definition of stress and strain:
σ = E * ε
Where:
- σ is the stress (force per unit area, in Pascals)
- E is the modulus of elasticity (Young’s modulus, in Pascals)
- ε is the strain (change in length divided by original length)
