végeselemanalízis

Végeselemanalízis, often abbreviated as FEA, is a numerical method used to predict how a product reacts to real-world forces, vibrations, heat, fluid flow, and other physical effects. It allows engineers to test and optimize designs before they are physically manufactured, saving time and resources. The core principle of FEA involves dividing a complex object or system into many smaller, simpler parts called finite elements. These elements are interconnected at specific points known as nodes.

The analysis then proceeds by applying mathematical equations to each individual element, considering its properties and the applied loads or conditions. By solving these equations for all the interconnected elements and their nodes, a system of equations is generated that represents the behavior of the entire structure. This system is then solved using computers to approximate the stress, strain, displacement, temperature distribution, or other performance characteristics across the entire model. FEA is widely used in various engineering disciplines, including mechanical, civil, aerospace, and biomedical engineering, for a broad range of applications such as structural integrity assessment, thermal analysis, and fluid dynamics simulations.
