Tartalmi leírás:
There is a wide interest in understanding phenomena related to thin and ultrathin surfaces, such as wrinkling, cresting or folding. The classical FĂśppl-von KĂĄrmĂĄn plate theory is extensively used to model such phenomena. Significant in-plane strains demand the extension of the classical FvK model. The extended theory predicts the disappearance of wrinkling in the case of rectangular, clamped, stretched sheets, which was verified on thin, polyurethane sheets. In this talk we further develop the model for curved surfaces and present problems, where the extension to the finite tangential strains is essential to investigate the arising wrinkling pattern. By numerical simulation of the governing nonlinear system of PDEs, we investigate the effect of the curvature of the reference configuration on the emerging wrinkling pattern and demonstrate that disappearance of wrinkles takes place on curved surfaces, as well.
