What is FEA?
Finite Element Analysis (FEA) is a computer based method of simulating/analyzing the behavior of engineering structures and components under different working conditions. It is an advanced engineering tool that is used in design and to augment/replace “experimental testing”.
Why FEA and how it will help you?
1. Allows virtual simulation to anticipate response of structure (stress developed and deformations) to applied loads at design stage. This allows fixing problems at design stage.
2.Increases the product reliability and robustness.
3.Reduces product development time and cost.
4. Reduces the number of prototype testing
5. Accepted validation procedure by different design codes/agencies.
Where FEA can be applied?
1. Structure analysis: a cantilever, a bridge, an oil platform…
2. Solid mechanics: a gear, a automotive power train
3.Dynamics: vibration of Sears Tower, earthquake and seismic waves , bullet impact, vehicle chassis
4. Thermal analysis: heat radiation of finned surface, temperature distribution in PCB
5. Biomaterials: dental implants, human organs and tissues.
Benefits of FEA
1. The availability of FEA enables engineers to achieve objectives which they otherwise could not, for instance making design modifications of highly stressed areas.
2.In almost any type of engineering endeavor, FEA saves time and money
3. FEA aids understanding of the structural behavior which helps to remove uncertainty and unnecessary pessimism.
