# The Concept of Finite Element Method (FEM) and Its Applications

Finite Element Analysis or Finite Element Method (FEM) is a computer-based numerical method, for calculating the behavior and strength of engineering structures. It is also used to calculate deflection, vibration, buckling behavior, and stress.

Basic Concept

Finite element method or FEM, solves a complex problem by redefining it as the summation of the solution of a series of interrelated simpler problems. In FEM, a complex structure is simplified by breaking it down into small elements. These elements are blocks, which form the structure.

Applications of FEM

✶ It is used for the description of form changes in biological structures (morphometrics), particularly in the area of growth and development.

✶ FEM and other related morphometric methods like the macro-element or the boundary integral equation method (BIE) are useful for assessment of complex shape changes.

✶ FEM and other related morphometric methods like the macro-element or the boundary integral equation method (BIE) are useful for assessment of complex shape changes.

✶ It is useful with structures containing potentially complicated shapes like dental implants and inherent homogeneous material.

✶ It is also useful to study stress distribution in tooth in relation to different designs.

✶ It is used in the area of optimization of the design of dental restorations.

✶ The type of predictive computer model described may be used to study the biomechanics of tooth movement, even though accurately assessing the effect of new appliance systems and materials without the need to go to animal or other less representative models.

✶ It is also used to predict and estimate the damages in electrical fields.

✶ It is also used in optimization of sheet metal blanking process.
