The elastic buckling stress for thin flat plate of length L, depth d and thickness t simply supported along four edges and loaded by bending stress distribution is given by . b) fcr = π2E/k. c) fcr = kπ2E/. d) fcr = kπ2E/. Correct Answer 12(1-μ2)(d/t)2

The elastic buckling stress for thin flat plate of length L, depth d and thickness t simply supported along all four edges and loaded by bending stress distribution, which varies linearly across its width is given by fcr = kπ2E/, where buckling coefficient k depends on aspect ratio L/d and the number of buckles along the plate.
