Abstract :
The analysis of thin rectangular orthotropic plate with two opposite edges clamped and the other two opposite edges simply supported (CSCS), carrying transverse loads was investigated in this study. The Ritz total potential energy functional was used. The minimization of the total potential energy functional produces the expression for the coefficient of deflection. The coefficient of deflection was used to obtain equation for the maximum lateral load of an orthotropic thin rectangular plate based on allowable deflection. Also, equation for the maximum lateral load of an orthotropic thin rectangular plate based on allowable stress was developed.Developed stiffness coefficients were substituted in the lateral load equations to obtain the maximum lateral load values for a CSCS plate. Numerical examples using permissible deflection of 10mm and yield strength of 250MPa, plate thickness (varying from 5mm to 12.5 mm with 0.5mm intervals) were done to determine the maximum lateral loads corresponding to an orthotropic thin rectangular CSCS plate carrying transverse loads (when n1 = Ey/Ex = 0.7 and n2 = G/Ex = 0.41) for aspect ratios (b/a) of 1.0, 1.25 and 1.50.
