Sufficiently smooth nonlinear PDE problems may be addressed through the higher order derivative computations of the so-called Asymptotic Numerical Method (ANM). In this paper, we theoretically discuss the generic solution of nonlinear residual equations. We then propose a Matlab implementation of the ANM based on Automatic Differentiation which allows for significant improvements in genericity and ease of use. The Diamant toolbox we construct is applied to the study of the geometrical nonlinear behavior of a laminated glass beam. Numerical results and experimental performances demonstrate the efficiency of the Diamant tool.
