     Consider a composite material plate of dimensions 0 lessthanorequalto x lessthanorequalto a, 0 lessthanorequalto  y lessthanorequalto  b, of thickness h, composed of an E Glass/epoxy, which is modeled as being simply supported on all four edges. It is part of a structural system, which is subjected to a hydraulic load as shown below.  The load is p(x, y) = rho y where rho is the weight density of the water.  To utilize the Navier approach determine B_mn which is given by  B_mn = 4/ab integral_0^a integral_0^b p (x, y) sin (m pi x/a) sin (n pi y/b) dy dx.  At what value of x will the maximum deflection occur?  At what value of x will the maximum stress sigma_x occur?
