ABSTRACTA semi analytical fully discretised finite strip method is developed to investigate the pre buckling and local buckling of viscoelastic plates with different boundary conditionssubjected to time dependent loading The mechanical properties of the material areconsidered to be linear viscoelastic by expressing the relaxation modulus in terms of Pronyseries The fully discretised finite strip equations are developed using a two pointrecurrence formulation which leads to a computationally superior formulation Timehistory of maximum deflection of plates with different end conditions is calculated Theeffect of unloading on of plates is evaluated Moreover a nonlinear approach is used tocalculate the critical load of plates subjected to in plane compressive loads The effects ofthickness length of plate and transverse loading on critical buckling load are also studied In addition the finite strip method is developed using bubble functions The displacementfunctions of plate are evaluated using a continuous harmonic function series that satisfiesthe boundary conditions in the longitudinal direction and a piecewise interpolationpolynomial in the transverse direction Finally the first shear order theory of plates is usedto evaluate the maximum deflection and critical load of viscoelastic moderately thickplates
