Parametric Study of Dynamic Wrinkling in a Thin Sheet on Elastic Foundation

Abstract: This work presents an approximate analytical study of the problem of dynamic wrinkling of a thin metal sheet under a specified time varying tension. The problem is investigated in the framework of the dynamic stability of a nonlinear plate model on elastic foundation which namely takes into account the nonlinear mechanics of mid-plane stretching and the dependence of the membrane force on this mechanics. The plate is assumed to be a wide rectangular slab, hinged at two opposite ends and free at the long ends, … Show more

“…In earlier work, we fabricated and characterized free-standing SBS thin films with thicknesses of hundreds of nanometers. , Their low elastic modulus and thickness let them conform extremely well to biological tissues (e.g., the skin). Notably, the flexural rigidity of a thin film, which describes its resistance to bending, is proportional to the cube of its thickness . Thus, the flexural rigidity of SBS thin films can be changed by changing its thickness.…”

“…The surface conformability of the sheet-type material depends on its flexural rigidity ( D ); a low flexural rigidity provides mechanically conformable adhesion to the rough surface of biological tissues . The flexural rigidity is calculated by the following equation: where E , t , and ν are Young’s modulus, thickness, and Poisson’s ratio of the sheet-type material, respectively . Since the flexural rigidity is in proportion to Young’s modulus and the cube of the thickness, the reduction of the thickness can drastically decrease the flexural rigidity and should be the most effective approach to enhance the conformability.…”

“…Одним из самых интересных элементов деформационного рельефа являются гофрированные структуры (складки). Их морфология очень разнообразна, и они проявляются в различных условиях [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Гофрирование часто в качестве нежелательного эффекта сопровождает процессы обработки металлов давлением.…”

“…Подобные результаты независимо получены и описаны в работе [8]. На образование гофрированных структур и сморщивание при механическом нагружении указывается в работах [9,10]. О формировании гофрирования ( " сморщивания") при деформации пленок на подложках сообщается в ряде работ, например [11][12][13][14][15].…”
