AUBURN UNIVERSITY Department of Civil Engineering CIVL 7690 Analysis of Plate and Shell Systems Final, Take Home, Due August 4, 2009 1. A simply supported semi-infinite plate shown below is free at the cut-off edge. A vertical line loading of a sinusoidal distribution is applied at the free edge. Derive a general expression for the deflection and the maximum bending moments. If 0 0.1 k/in, q = 100 in, a = 1 in, E=29,000 ksi, and 0.3 t μ = = , determine max max max max , , , and x y x w M M R and plot the variation of max max max , , and y x w M M versus x . 2. A square plate of dimension “a” is simply supported on two side boundaries and fixed at

Unformatted text preview: the top and bottom. The plate is subjected to a linearly varying compressive load, x N , resulting from a pure bending plus axial compression as shown in the sketch. Using the energy method discussed in the class, determine the critical load. Assume the displacement function as single waves for both x- and y-directions reflecting the fixed condition in the y direction. y y x ( 29 sin y p y q a = free edge x a a a N s.s. s.s. 1 2 N fixed fixed...
