Free Vibration and Buckling Analysis of Sandwich Panels with Flexible Cores Using an Improved Higher Order Theory
In this paper, the behavior of free vibrations and buckling of the sandwich panel with a flexible core was investigated using a new improved high-order sandwich panel theory. In this theory, equations of motion were formulated based on shear stresses in the core. First-order shear deformation theory was applied for the procedures. In this theory, for the first time, incompatibility problem of...
متن کاملLQG vibration control of sandwich beams with transversely flexible core equipped with piezoelectric patches
The purpose of this paper is control of simply supported flexible core sandwich beam's linear vibration equipped with piezoelectric patches under different loads. The effects of external forces imposed on sandwich beam can be reached to a minimum value by designing an appropriate controller and control the beam's vibration. Three-layer sandwich beam theory is used for analytical modeling of san...

متن کاملLS-DYNA Impact Simulation of Composite Sandwich Structures with Balsa Wood Core
The impact damage response of balsa core sandwich composite plates with S2-glass/ epoxy reinforced facesheets is evaluated by impacting them with a spherical steel projectile at single impact locations. The impact damage can significantly reduce the structural integrity and load bearing capacity of a composite structure. Under high velocity impact loading, laminated composites experience signif...
متن کاملNon-linear Response and Dynamic Buckling Analysis of a Cylindrical Sandwich Panel with a Flexible Core under Blast Loading
In this paper, three-dimensional displacement response of a cylindrical sandwich panel with compressible core under the action of dynamic pulse loading is addressed using the extended high order sandwich panel theory. Also, local dynamic pulse buckling of facesheets is studied by considering the Budiansky-Roth buckling criterion. It is assumed that the sandwich panels consist of orthotropic fac...
