Topic: Energy Method for the bending of thin plates Example (exact solution): Consider a rectangular plate with simply supported edges and subjected to a uniformly distributed transverse load of intensity 90. Determine the maximum value of deflection if the deflection is known to have a shape function. Using Python Programming, construct a code using the solution below. sin sin W Solution: Total energy of the plate as summation of internal (strain) energy and potential energy of load is Da'w aw awaw aw U + V = x2 * @ya -2(1 - v) x@y2 wqo drdy Substitute deflection w into the energy equation yield nity U + V [[{3X=[-3-7) *** max -2(1 - V) ab sin 2 MEX ny sin? b mex cos a COS?
