| Abstract | This report is concerned with methods leading to automated adaptive numerical solutions to geometrically non-linear shell--type problems. In particular, procedures for improving the accuracy, the reliability as well as the computational efficiency of the finite element solution are of primary interest. This is addressed through use of h--adaptive mesh refinement based on a posteriori error estimation and self-adaptive methods in global incremental--iterative processes. Integration of h--adaptive finite element methods with non-linear solution algorithms makes it possible to maintain a prescribed solution accuracy efficiently without user intervention throughout the process of a non-linear analysis. The above objective is addressed by considering the four--noded shell element developed by Simo and co-workers, which has been implemented in the non-linear finite element code FENRIS. Error estimation by the Zienkiewicz--Zhu method is employed to provide guidance for an h--adaptive mesh re... |
