Abstract
The project is concerned with research in the field of computational modelling in nonlinear continuum mechanics. Two main tasks of the project are: (a) theoretical and numerical (i.e. finite element) development of novel models for materially and geometrically nonlinear analysis of thin-walled shell-like structures; and (b) development of specialized nonlinear material models in order to obtain a reasonably realistic simulation of mechanical behaviour of different materials - in particular fibre-reinforced composites, metals and reinforced concrete. All together, it has to result in a world competitive computational model for the analysis of shell-like structures. The model, based on the finite element model, should be free from many known numerical difficulties (numerical instabilities, numerical locking, mesh sensitivity, etc.), and it should exhibit a quadratic rate of convergence.
