Finite Element Analysis software is a computerized system that has the capability to predict, how a certain product will react to any forces in the real world, to heavy vibration, fluid low, hear or any other kind of physical effect. In other words, this will show you whether or not a product that you have designed will break. It can also indicate whether the product will wear out or whether it will continue to work in the way that it was originally designed. This is essentially the analysis but in the world of product development, this feature allows you to predict what will happen when the product is actually used.
How does it work?
Finite Element Analysis works through breaking down a real object into a finite number of really small elements, like cubes for example. In fea analysis software, mathematical equations will help you predict the behavior of each of the elements. The computer will the do the calculation for you and add up the individual behaviors in each of the elements to predict the actual and final behavior of the complete product as a whole. Some of the many physical effects that Finite Element Analysis lets you test out include mechanical stress and vibrations, motion, fatigue, fluid flow, heat transfer, electrostatics and molding of plastic injections.
What are applications of this analysis?
The applications of this analysis are many. However some of the most common ones can be divided into five main sections as stress analysis, seismic analysis, thermal analysis, vibration analysis and impact and crash analysis. Each of these are in turn divided into many subsections again. For example thermal analysis can be divided into conduction, radiation, convection and conjugate heat transfer. Seismic analysis can be divided into response spectrum, transient dynamics and equivalent static. Impact and crash analysis can be divided into equivalent static and short duration explicit stimulation. These are just a few of the subsections here and you can therefore understand how many areas this analysis can be applied in.
How has this analysis helped?
This a powerful and efficient design tool and is has helped to considerably improve the standards of engineering and also the methodology used in the designing process across many applications in the industry. The advent of Finite Element Analysis has considerably lowered the amount of time that is usually taken from concept to prototype and finally to manufacture. This analysis also primarily relies on improving the initial designs through prototype tests. This has also improved the delivery times over a long period of time. It has enabled manufacturers to enhance the integrity and the longevity of products that they make.
