ADVANCED FLEXURAL ANALYSIS OF CSSS PLATES USING ORTHOGONAL DISPLACEMENT EQUATIONS
Abstract
The flexural analysis of thick plates, a crucial aspect in structural engineering, has historically relied on classical plate theory (CPT) and subsequent modifications to address its limitations, particularly in accurately predicting the behaviour of thick plates. This study proposes a novel approach using polynomial displacement functions to enhance the analysis of thick rectangular plates subjected to various loading conditions. Building upon previous research, the theoretical framework incorporates polynomial shear deformation functions and boundary conditions to develop comprehensive models for flexural analysis. Through numerical examples and comparisons with existing theories, the efficacy of the proposed method is demonstrated, offering engineers a more efficient and accurate tool for analysing thick plate structures.
