Abstract:

The p-version of the finite element method is a new approach to finite element analysis which has been demonstrated to lead to significant computational savings, often by orders of magnitude this approach was formerly called the constraint method the new term p-version is more descriptive. Conventional approaches called the h-version generally employ low order polynomials as basis functions. Accuracy is achieved by suitably refining the approximating mesh. The p-version uses polynomials of arbitrary order p is or 2 for problems in plane elasticity where CO continuity is required and polynomials of order p is or 5 for problems in plate bending where C1 continuity is required.
