What Equations Are Solved in Different FEA Analyses?

[sunny110]

Hello; I have a basic question from FEA theory.
What are the basic equations solved during ..
a. Linear Static Analysis
b. Nonlinear analysis
b. Dynamic Analysis
c. Crash analysis
d. CFD
e. NVH

I also have a look at a wikipedia article about FEM (http://en.wikipedia.org/wiki/Finite_element_method) but my question is what is the basic equation solved during NVH analysis?

As you know, in linear static analysis the basic equation is Kd=f; or for modal analysis we have M*ddot(x)+ K*x=0;

Thanks in advance.

You have asked for a pretty wide scope of information. It's like asking someone to list every equation used in physics in a blog post.

In some of the topics you list, there may be more than one equation or type of equation which is being solved.

The finite element method is a tool. If you want to know what equations apply to what topic (CFD, NVH, etc.), then study that particular subject in more detail.

Thanks for your reply. I followe your advice but could you introduce me some fundamental references?

You could take a look at the references at the end of the wikipedia article on the Finite Element Method. It should be a good starting point.
