Finite Element Analysis of Plate and Shell Structure

The plate and shell structure is a structure in which the dimension in the thickness direction is much smaller than…

Plane Stress Elements

They must be plane, i.e., the coordinates of the element nodes must be in one flat plane, the xy plane of the element.…

ONE DIMENSIONAL ELEMENT

Bar and beam elements are considered as One Dimensional elements. These elements are often used to model trusses and frame…

How the FEM work

Jacobian in FEA

In the Finite Element Method, an element’s Jacobian Matrix relates the quantities wrote in the natural coordinate space and the…

What is the difference between serendipity family elements and isoparametric elements in finite element analysis?

In the Finite Element Method we use several types of elements. These elements can be classified based upon the dimensionality…

Springs and Elements

We already discussed, that “spring equations” are “coupled”. You can’t simply say that a single “spring equation” describes the force/displacement…

What are Nodes and Elements in Finite Element Analysis?

Nodes and Elements are the very backbones of Finite Element Analysis. You will use them in every analysis you will…

Isoparametric Elements

As mentioned above, to form a mesh over a general region the elements must be allowed to take more general…
