FEA or Finite Element Analysis is the simulation of a real phenomenon using a mathematical technique. This mathematical technique is referred to as FEM or Finite Element Method. FEA is a core process for mechanical engineers and various other disciplines used to solve complex equations.
FEA is one of the essential principles for the development of simulation software. Engineers also use it to run virtual experiments and reduce the number of prototypes. This blog will serve as a comprehensive guide to FEM.
What is Finite Element Analysis?
Finite Element Analysis is a tool to find solutions to varying equations describing kinematics, dynamics, and geometry. Engineers find these solutions by approximating the varying equations with simple and discrete equations.
Why is it Used?
Finite Element Analysis is used widely in mechanical engineering as one of the most popular analysis methods. It is also used in various engineering disciplines, including civil, structural, geotechnical, and aerospace engineering, to analyze dynamic behavior such as vibration in a structure or static change such as the stress in a component. FEA also benefits biomechanics and a multitude of other areas that involve stress analysis.
The fame of finite element analysis is the high accuracy it provides on complex forms that can’t be achieved otherwise. It also enables non-linear behavior, like friction and contact; these can’t be molded using linear analysis. To be precise, Finite Element Analysis allows the modeling of almost anything that can withstand a static load.
Benefits of FEA
The details for the mechanism of a system are usually not fully available or known. FEA can address this problem by solving every element separately. One of the many advantages of this approach is that once elements are solved, various systems can be analyzed simultaneously with a little additional effort.
Finite Element Analysis allows the use of FEM to analyze complex real-world situations. For instance, a designer can test several designs for a screw. Once the most appropriate design is chosen, the results for each design can be displayed and compared for further development.
Another major advantage is that FEM is computationally robust and fast. Finite Element Analysis requires comparatively easier algebraic manipulation, making it simpler and quicker to reach a solution. Furthermore, ongoing issues with sufficiently small elements can be easily solved without putting much effort into them.
