Abstract

This paper shows a 6-node curved nonlinear co-rotational shell element with nonlinear models. Vectorial rotational variables are used in this co-rotational element, so that a symmetric stiffness matrix can be obtained and the updating procedure is simplified. In order to investigate the behaviour of structures with nonlinear material constitutive relationships, layered model is adopted so that material properties varying along the thickness of shell structures can be simulated independently. Since co-rotational approach is adopted, the material constitutive model based on stress-strain relationship can be used directly in each elemental local coordinate system. Several numerical examples with different constitutive relationships are presented to verify the formulations.
