Buckling of laser-welded sandwich panels: Ultimate strength and experiments

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...

Finite 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...

Ultimate Strength Analysis of Normal and High Strength Concrete Wall Panels with Varying Opening Configurations

Laser Welded versus Resistance Spot Welded Bone Implants: Analysis of the Thermal Increase and Strength

INTRODUCTION The first aim of this "ex vivo split mouth" study was to compare the thermal elevation during the welding process of titanium bars to titanium implants inserted in pig jaws by a thermal camera and two thermocouples. The second aim was to compare the strength of the joints by a traction test with a dynamometer. MATERIALS AND METHODS Six pigs' jaws were used and three implants were...
