Buckling and crushing behavior of foam-core hybrid composite sandwich columns under quasi-static edgewise compression

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...

Edgewise Compression Behavior of Three-Dimensional Integrated Woven Sandwich Composite Panels

Quasi-static Axial Compression of thin-walled Circular Composite Tubes

Assessing the behavior of composite structures which are subjected to impact loads is one of the important subjects in the field of mechanical sciences. Using thin-walled tubes which collapsed and absorbed the impact energy is a well-known method to prevent damages to the other parts of the structures. In this paper, deformations, crushing length, peak load, mean force and energy absorption cap...

Mechanical behavior and failure of composite pyramidal truss core sandwich columns

A series of analytical and experimental investigations is presented to study the response and failure of pyramidal truss core sandwich panels made of carbon fiber composite under axial compression. In the analytical part of the study, three failure modes: (i) Euler or core shear macro-buckling, (ii) face wrinkling, and (iii) face sheet crushing, were considered and theoretical relationships for...
