Abstract:The bending of laminated plates is considered using higher-order transverse shear deformation theory. The principle of virtual work is used to derive a new set of seven governing equations and corresponding boundary conditions. These equations, combined with eighteen relationships between the resultant stress and displacement components, compose a system of first-order partial differential equations that is solved by the generalized differential quadrature method. Numerical results for laminated plates with a … Show more
“…Using the procedure provided in [30], the relationship between strain components and seven field variables for HSDT plate in the matrix form can be written as In Eq. (2), two new unknown functions w i ¼ ∂w=∂x i ði ¼ 1; 2Þ have been introduced to simplify stiffness matrix calculations.…”

“…Then, decomposing the stiffness matrix in order to use different integration points for numerical integration along with a linear basis for MLS approximation can produce accurate results even for thin plates. Table 3 shows the comparison of the results using proposed approach (EFG) versus FEM [34] and the Generalized Differential Quadrature (GDQ) proposed in [30]. Both FEM and GDQ utilize HSDT.…”
