Finite Element Analysis
(Finite Element Analysis) A mathematical technique for analyzing stress, which breaks down a physical structure into substructures called "finite elements." The finite elements and their interrelationships are converted into equation form and solved mathematically.
Graphics-based Finite Element Analysis software can display the model on screen as it is being built and, after analysis, display the object's reactions under load conditions. Models created in CAD packages can often be accepted by Finite Element Analysis software.
Finite element analysis a numerical technique
Finite element analysis (FEA) or finite element method (FEM) is a numerical technique for solution of boundary-value problems. While being an approximate method, the accuracy of the Finite Element Analysis method can be improved by refining the model using more elements and nodes.
A common use of Finite Element Analysis is for the determination of stresses and displacements in mechanical objects and systems. However, it is also routinely used in the analysis of many other types of problems, including those in heat transfer.
tructures can be analyzed for small deflection and elastic material properties (linear analysis), and for simultaneous large deflection and plastic material properties.
By plastic material properties, we mean that the structure is deformed beyond yield of the material, and the structure will not return to its initial shape when the applied loads are removed.
Optimization of an engineering design is an improvement of a proposed design that results in the best properties for minimum cost.
