The Basic Principle of Finite Element Analysis

0 Comment

The distribution of meshes is based on the type of problem. If a location requires very refined analysis this region could have very fine meshes (Widas, 1997). A typical finite element application is shown below. Here, the finite element model of the problem is shown in figure 1. The material is divided into small triangle shaped elements and hence it can be said that the body is meshed using triangular elements.
The FEA software consists of different type of elements that could be used in the analysis. The element refers to the geometrical shapes that are used to mesh the system. Some of the types of elements used usually used are rod elements, beam elements, plate/shell/composite elements and Solid elements
The process of dividing the problem element into the fine grids is known as meshing. The mesh would consist of similar elements or a combination of different elements. Like for an irregular body the using square or rectangular elements might be useful in proper division of the domain space into small elements. This disadvantage shall be overcome by a different type of elements like triangular elements to wards the boundary or irregular side for proper geometrical matching between the finite element model and the actual physical body. …
This disadvantage shall be overcome by a different type of elements like triangular elements to wards the boundary or irregular side for proper geometrical matching between the finite element model and the actual physical body. Another important aspect that needs to be considered is the size of meshes that are used for the process of discretisation. The size of meshes could be course, large and well spread, or fine, small size and closer placed.&nbsp.
