Buckling of a double sector thin elastic plate: Analytical solution

• A novel geometry is proposed, which can buckle from an initial planar configuration into a complex 3D shape under tensile load. More importantly, the parametrized closed-form solution of the deformed geometry is obtained analytically. • The mechanical analysis of the buckling and post-buckling behavior is also provided. • This closed-form solution can be used to benchmark either a numerical simulation of buckling or a Stereo Digital Image Correlation (Stereo-DIC) code.
