Vectorial Padé approximants in the Asymptotic Numerical Method
Keywords:
vectorial Padé approximants, asymptotic numerical method, quadratic approximants, non-linear elastic shellsAbstract
In this paper, we present and discuss some techniques to define vectorial Padé approximants and quadratic approximants in the Asymptotic Numerical Method (ANM). For this purpose we have to orthonormalize the basis generated by the ANM. We shall discuss the influence of the orthonormalization procedure. We give some numerical comparisons of these techniques on non-linear elastic shells problems.
