Buckling and vibration of shear deformable prismatic plate structures by a complex finite strip method

摘要: Abstract A finite strip method is presented for the determination of buckling stresses and natural frequencies vibration prismatic plate structures assembled from flats, which generally are laminates fibre-reinforced composite material. The single-term type, corresponding to assumption sinusoidal longitudinal spatial variation displacement force quantities. Anisotropic material behaviour applied in-plane shear stress accommodated by expressing field in terms complex out-of-plane properties flats based upon use first-order deformation theory. family models described a sub-structuring procedure utilised reduce size eigenvalue problem. Presented numerical results reveal high accuracy good convergence characteristics method, as well indicating influence through-thickness effects range circumstances.
