Structural Response of Polyethylene Foam-Based Sandwich Panels Subjected to Edgewise Compression

Structural Response of Polyethylene Foam-Based Sandwich Panels Subjected to Edgewise Compression

This study analyzes the mechanical behavior of low density polyethylene foam core sandwich panels subjected to edgewise compression. In order to monitor panel response to buckling, strains generated in the facesheets and overall out-of-plane deformations are measured with strain gages and projection moiré, respectively. A finite element (FE) model simulating the experimental test is developed. ...

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

Optimization of Composite Sandwich Cover Panels Subjected to Compressive Loadings

An analysis and design method is presented for the design of composite sandwich cover panels that includes transverse shear e ects and damage tolerance considerations. This method is incorporated into a sandwich optimization computer program entitled SANDOP. As a demonstration of its capabilities, SANDOP is used in the present study to design optimized composite sandwich cover panels for transp...

Metallic sandwich panels subjected to multiple intense shocks

The mechanical response and fracture of metal sandwich panels subjected to multiple impulsive pressure loads (shocks) were investigated for panels with honeycomb and folded plate core constructions. The structural performance of panels with specific core configurations under multiple impulsive pressure loads is quantified by the maximum transverse deflection of the face sheets and the core crus...

Effect of Cyclic Compression Loading On Crushing Response of Polymer Based Composites Sandwich Panels

The objective of work was focused to investigate microstructure of polyurethane foam and cyclic crushing strength of its sandwich structure which made of sisal / coir / bamboo / glass fabrics as reinforcement with polyester resin to form composites skin. The tested sandwich panels were constructed four type of FRP faceplates made of sisal / coir / bamboo / glass fiber reinforcements impregnated...
