Abstract Abstract: Using the finite element software ANSYS, a physical model is developed for the elasticity analysis of the sandwich plates reinforced by resinic columns. The SOLID82 elements are used to calculate buckling, free vibration and transient response. The effects of the material properties and the distributions of the resinic columns on the buckling loads and natural frequencies are studied. The displacement response of the plates under the transient shock is also discussed. The results show that the resinic columns have some contributions to the mechanical properties of the sandwich plates. The modulus influence of resinic columns on buckling and vibration of the composite plates is small. However, the distribution effect of the resinic columns on the mechanical properties of the composite plates is considerable.
