A variationally consistent membrane wrinkling model based on spectral decomposition of the strain tensor
Daobo Zhang, Josef Kiendl
We propose a novel variationally consistent membrane wrinkling model for analyzing the mechanical responses of wrinkled thin membranes. The elastic strain energy density is split i…

A fully explicit isogeometric collocation formulation for the dynamics of geometrically exact beams
Giulio Ferri, Josef Kiendl, Alessandro Reali +1
We present a fully explicit dynamic formulation for geometrically exact shear-deformable beams. The starting point of this work is an existing isogeometric collocation (IGA-C) form…

An efficient active-stress electromechanical isogeometric shell model for muscular thin film simulations
Michele Torre, Simone Morganti, Alessandro Nitti +4
We propose an isogeometric approach to model the deformation of active thin films using layered, nonlinear, Kirchhoff Love shells. Isogeometric Collocation and Galerkin formulation…
