Local Buckling of Web-Core and Foam-Core Sandwich Panels
Sandwich construction is widely accepted as a method of construction especially in the aircraft industry. It is a type of stressed skin construction formed by bonding two thin faces to a thick core, the faces resist all of the applied edge loads and provide all or nearly all of the required rigidities, the core spaces the faces to increase cross section moment of inertia about common neutral ax...
متن کاملFinite Element Modeling of the Buckling Response of Sandwich Panels
A comparative study of different modeling approaches for predicting sandwich panel buckling response is described. The study considers sandwich panels with anisotropic face sheets and a very thick core. Results from conventional analytical solutions for sandwich panel overall buckling and face-sheet-wrinkling type modes are compared with solutions obtained using different finite element modelin...
متن کاملBuckling Analysis of Composite Lattice Cylindrical Shells with Ribs Defects
In this paper, the buckling behavior of a composite lattice cylindrical shell is studied and effects of rib defects on the distribution of stress field and buckling response of the shell is investigated. A three dimensional finite element buckling analysis of the lattice shell is carried out using ANSYS suit of program. Geometrical data and material properties of the shell are obtained from the...
متن کاملFree 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 کاملDesign of Sandwich Panels With Prismatic Cores
The paper focuses on optimization of lightweight sandwich panels with prismatic cores subject to bending loads in the two principal in-plane directions. Comparisons are made with optimal designs of panels with corrugated cores: a limiting case. When optimized for loading transverse to the prism axis, prismatic panels outperform those with corrugated cores, especially at lower loads. In contrast...
