Finite Element Analysis Definition

Engineers use it to reduce the number of physical prototypes and experiments and optimize components in their design phase to develop better products faster while saving on expenses.

Finite element analysis definition. Elements may have physical properties such as thickness coefficient of thermal expansion density young s modulus shear modulus and poisson s ratio. It is necessary to use mathematics to comprehensively understand and quantify any physical phenomena such as structural or fluid behavior thermal transport wave propagation and the growth of biological cells. The finite element analysis fea is the simulation of any given physical phenomenon using the numerical technique called finite element method fem. Finite element analysis is a type of computer based analysis which calculates variations of quantities such as temperature or stress in a body by dividing it into small parts with no spaces between them.

Finite element analysis shows whether a product will break wear out or work the way it was designed. Finite element analysis fea is a type of computer program that uses the finite element method to analyze a material or object and find how applied stresses will affect the material or design. Fea can help determine any points of weakness in a design before it is manufactured. The finite element method fem is a numerical technique used to perform finite element analysis of any given physical phenomenon.

In the fem the structural system is modeled by a set of appropriate finite elements interconnected at discrete points called nodes. Typical problem areas of interest include the traditional fields of structural analysis heat transfer fluid flow mass transport and electromagnetic potential. The analysis includes bringing the product in contact with force heat vibration fluid flow and other such physical conditions. To solve a problem the fem subdivides a large system into smaller simpler parts that are called fini.

The finite element method is the most widely used method for solving problems of engineering and mathematical models. The fem is a particular numerical method for solving partial differential equations in two or three space variables. Physical problems range in. Finite element analysis fea is a computerised method for predicting how a product reacts to real world forces vibration heat fluid flow and other physical effects.
