This research focuses on the study and comparison of the thermomechanical bending behavior of porous advanced composite plates, particularly functionally graded materials (FGM), where the presence of porosity significantly influences their structural performance. A refined shear deformation theory is developed to analyze the bending response of porous FGMs under thermomechanical loads. The proposed model introduces a novel transverse shear function, separating transverse displacements into bending and shear components. This innovative approach simplifies the analysis, requiring fewer unknowns and eliminating the need for shear correction factors, thereby reducing computational costs compared to traditional theories such as first-order shear deformation theory (FSDT), higher-order shear deformation theory (HSDT), sinusoidal shear deformation theory (SSDT), and quasi-3D theory. The study examines the bending response of porous FGMs composed of various materials, including FGM 1 (Aluminum/Zirconia), FGM 2 (Ceramic/Zirconia), FGM 3 (Titanium/Silicon Carbide), FGM 4 (Stainless Steel/Zirconia), FGM 5 (Copper/Alumina), and FGM 6 (Nickel/Silicon Nitride). The results derived from the proposed theory are systematically compared with those obtained from other established theories to demonstrate its accuracy and computational efficiency. This work provides valuable insights into the behavior of porous FGMs and highlights the potential of the refined shear deformation theory for future applications in structural engineering.
