Pascal’s Triangle for determining the appropriate displacement field in finite element analysis

For the convergence of solution in finite element analysis, the assumed displacement field should be isotropic . This is achieved if the components of the displacement field are complete polynomials. This is achieved by using PASCAL’s TRIANGLE. It is a…
