Geometric nonlinearity assignment, Due date: May 2

(All geometries are located in J:\users\public\geom_non_hw.mf*) A thin aluminum plate is to be analyzed for out-of-plane linear buckling as well as non-linear behavior. The plate is restrained along the edges AB and CD. A uniform distributed downward load of 1.65 N/mm is applied to the edge EF. Use the SDRC Aluminum 6061-T6. Use a thickness of 0.25-mm Hint: To ensure the out-of-plane buckling behavior, introduce a small (about 1/100 of the actual applied load) out of plane load along the edge EF.
