What is FEA? FEA (Finite Element Analysis) is a method of estimating how a part or assembly will behave when real life loads such as gravity, pressure, torque or force are applied. At Project Engineering, we carry out FEA on 3D CAD models of our designs to determine how they will behave under load. Typically an FEA study will be used to determine; the design stress, strain, displacement and factor of safety. Our FEA software will display these results graphically in a colour coded model of the design.
Where is it used? FEA is widely used across all engineering disciplines. At Project Engineering we generally use FEA to;
- Verify a proposed design meets the client's specifications,
- Evaluate a design prior to expensive physical manufacture and testing,
- Determine the cause of failure and identify corrective design modifications in the case of real-life part failure
What are the benefits? By examining critical parts during the design process, areas of possible weakness can be identified and reviewed at an early stage. By carrying out FEA on the Digital Prototype, components can be accurately sized and manufactured parts can be optimised for material usage and performance. Excess material can be identified and removed, reducing the product’s material cost, weight and transport cost.
Why Project Engineering? At Project Engineering have built up years of educational and industrial experience applying the sophisticated methods of FEA outlined above. Our engineers have both the theoretical & practical knowledge to ensure that results are as accurate as possible, data is analysed in the correct manner & we can suggest modifications that will have a real and beneficial impact on your product.
The theory behind FEA… FEA is based on the assumption that the solution to any complex engineering equation can be approximated by subdividing the problem into a finite number of smaller more manageable equations.
The FEA software does this by simplifying a complex design into multiple (thousands) of smaller points called nodes which make a grid called a mesh. Each element is individually examined as a component using simplified equations. Nodes are assigned at a certain density throughout the material depending on the anticipated stress levels of a particular area. Regions which will receive large amounts of stress usually have a higher node density than those which experience little or no stress. Points of interest may consist of: fillets, corners, complex detail, and high stress areas.
