FEA = finite element analysis

What two types of shape functions are most commonly used in FEA? Why?

The two types of shape functions used in FEA

are

A) Linear shape function

b)Quadriatic shape function

Linear shape function is used when two nodes are used and only linear equation is sufficient to interpolate the function.

Quadriatic equation is used when an additional midside node is used.
