Numerical simulation of the behaviour of a multi-jointed structure
Résumé
The paper presents the modelling of imperfect joints between plates by accounting for both the clearance and the rotative friction. This model is used to underline some special features of the static behaviour of rolling shutters. The numerical implementation is performed with an hybrid formulation coupled with a Newton-type method. The numerical instabilities may be easily controlled by applying some criteria from analysis of very simple examples.
