CONSTITUTIVE MODELS FOR STRONGLY CURVED BEAMS IN THE FRAME OF ISOGEOMETRIC ANALYSIS

Submitted by Flavio Stochino on

The current development of the isogeometric approach in various fields of mechanics is explained by the high-accuracy results which can be achieved at a reduced computational cost by codes based on non-uniform rational B-splines (NURBS). In the case of strongly curved beams the simple diagonal de Saint-Venant’s constitutive model can lead to significant errors as it has been reported in the classic literature. Other models such as Winkler’s have been proposed and seem more suitable for these kinds of structures.

Residual Stresses and Poisson’s Effect Drive Shape Formation and Transition of Helical Structures

Submitted by zichen on

Strained multilayer structures are extensively investigated because of their applications in microelectromechanical/nano-elecromechanical systems. Here we employ a finite element method (FEM) to study the bending and twisting of multilayer structures subjected to misfit strains or residual stresses. This method is first validated by comparing the simulation results with analytic predictions for the bending radius of a bilayer strip with given misfit strains.
