Shear deformation in thermal vibration analysis of laminated plates by the GDQ method

摘要: Abstract The interlaminar stresses and deflections in a laminated rectangular plate under thermal vibration were determined by using the generalized differential quadrature (GDQ) method involving effect of shear deformation. approximate stress deflection solutions are obtained sinusoidal temperature load for layer cross-ply laminate. Numerical results show that maximum at center position laminate increasing with side-to-thickness ratio a/h ∗ value decreasing, especially region ⩽20 . GDQ provides an efficient calculating multi-layered subjected to including deformation few grid points.
