In FEM, What is the number of displacement polynomials necessary for finding displacements in a linear triangular element?
In FEM, What is the number of displacement polynomials necessary for finding displacements in a linear triangular element? Correct Answer 2
The number of displacement polynomials for an element is equal to the degrees of freedom of each node of the element. A linear triangular element has three nodes and two degrees of freedom at each node. Thus, the total number of displacement polynomials necessary for finding displacements is two.
