000014343 520__ $$2eng$$aTorsional deformations in annular thin sheets is a challenging problem in theoretical mechanics due to destabilizing torsional shearing stresses that result in wrinkling. Determining the location, pattern, and evolution of wrinkles in these problems has important applications in design and is an area of increasing interest in the fields of physics and engineering. In this work, nondimensional nonlinear von Karman buckling equations are established, which are solved by the finite difference method to acquire the post-wrinkling characteristics. The proposed theoretical model can accurately predict the critical wrinkling behavior and post-wrinkling characteristics of the annular thin sheets, which are verified by the experimental measurement based on the digital image correlation (DIC) technique.
