Laminated Composite Plate, Modulus Ratio, Aspect Ratio, Analysis, Finite Element Method (FEM)
Laminated composite plate structures finds numerous applications in aerospace, military and automotive industries. The role of transverse shear is very important in composites, as the material is weak in shear due to its low shear modulus compared to extensional rigidity. Hence, an accurate understanding of their structural behaviour is required, such as deflections and stresses. In this paper, a number of Finite Element Analysis (FEA) have been carried out for various side-tothickness ratios and modulus ratios to study the effect of transverse shear deformation on deflection and stresses of laminated composite plates subjected to tensile load. The FEM results showed on the deflections and stresses, that the effect of coupling is to decrease the deflections with the increase in the modulus ratio and change in the stresses with the increase in the side-to-thickness ratio.
