Journal Article 2018 11 09 In this study, stress analysis of circular plate with variable thickness with clamped and simply-supported edge are presented. In the most previous research on the variable thickness plates, midplane symmetric plates were analyzed but as a first time in this study, by using two independent functions for top and bottom surfaces, transverse asymmetric plates can be analyzed. By using the combination of first order shear deformation plate theory and 3D elasticity method the shear and normal stress components such as transverse shear and normal stresses are extracted. For examination of the accuracy of the obtained results based on the presented analysis, the obtained results are compared with those obtained by 3D elasticity of ABAQUS software based on the finite element method. The comparisons show that the presented solution has very good accuracy and presented procedure for stress analysis of circular plates are very effective. Based on the presented procedure in this is study, 3D figures of stresses in the radial and thickness directions can be easily extracted and the stress components can be investigated more effectively.
