Finite Element Analysis

Finite element analysis (FEA) is getting a bigger role in development projects, mainly because it helps reduce expensive prototype testing. In addition, FEA highly contributes to improving product integrity. What is FEA analysis? Finite element analysis is a computerised method for predicting how a product reacts to real-world forces, vibration, heat, fluid flow and other physical effects. FEA highlights whether a product will break, wear out or work the way it was intended. It’s defined as an analysis, but in reality, it’s used in the product development stage to predict what’s going to happen when the product is actually used. FEA breaks down a real object into a huge number of finite elements, such as little cubes. The elements all have a mathematical defined relationship between force and displacement. Therefore, mathematical equations are used to help forecast the behaviour of each element. Then, a computer totals the individual behaviours to predict the performance of the object itself. What physical effects does FEA predict? Finite element analysis helps predict the behaviour of products affected by many physical effects, including: -Electrostatics -Fatigue -Fluid flow -Heat transfer -Mechanical vibration -Motion -Mechanical stress -Plastic injection moulding Using our extensive manufacturing knowledge, we can review your drawing prior to production. Therefore, ensuring you have a product design that reduces waste without compromising the strength and functionality of your part. We utilise our design expertise and FEA skills to evaluate and consider: -Uniform wall thickness -Soft lines -Smoothing -Solid profiles (if possible) -Pockets or channels -Decoration -Location of splits -Ejector pins -Gate positions -Date wheels -Wall thickness, flow and shrinkage -Die Fill -Mechanical performance vs ease of casting -FEA Analysis Case Study A client uses a solid aluminium bar which is loaded in the centre. The bar does not deform; however, it is expensive, and the client wants to save money.

Furthermore, our engineers can simulate reality whatever the situation or complexity. Direct results from our ability to carry out FEA analysis are profits with respect to time and also cost in the design phase. Likewise, it adds to the reliability of your product.
