In this work, some techniques are proposed to improve the usual Newton-Raphson Method (NRM) used in the numerical analysis of large strain viscoplastic problems. These techniques, based on the ΓΏrst-order perturbation technique, allow to deΓΏne an adaptive step strategy and to improve the trial soluti
This paper examines difficulties encountered when using the Green-Nagdi rate and presents an updated configuration formulation for problems dealing with large deformations. It is shown that a natural link can be established between the updated reference configuration and linearized updated Lagrangia
Well-known finite element concepts like the Assumed Natural Strain (ANS) and the Enhanced Assumed Strain (EAS) techniques are combined to derive efficient and reliable finite elements for continuum based shell formulations. In the present study two aspects are covered: The first aspect focuses on t
