light weight wood base sandwich panels have some special properties and their most important properties is high mechanical strength with its light weight. these panels can replace instead of traditional structural systems in iran. the purpose of this paper is investigating the mechanical properties of light weight wood base sandwich panels that have made from sunflower stalk wastes and particle...

The method for calculating the deflection of a web-core sandwich panel in its weak direction is based on complex shell and plate theory. A simple method was presented by assuming inflection points are located at the mid-span of the facing plate segment between two adjacent web cores. It also assumes that an inflection point also exists at the midheight of the web core. Based on these assumption...

USC’s work on sandwich structure acoustics began in 1998 and has evolved in close collaboration with the M.C. Gill Corporation, a leading manufacturer of sandwich panels for aircraft interiors. The work has had both an applied mission and an academic focus, and presents an example of university-industry collaboration can produce mutual benefit while advancing scientific understanding. Here, we ...

This paper presents an analytical investigation of the nonlinear vibration characteristics a single-phase functionally graded cylindrical shell panel with various porous metal cores. Porous constructions varying degrees porosity throughout their volume are known as materials (FGMs). These have wide range applications across several industries, including shipbuilding, automotive, biomedical, mar...

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...

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...

In the present work a non-linear dynamic response of a continuous sandwich beam with SMA hybrid composite face sheets and flexible core is analyzed taking into account the phase transformation and also the material non-linearity effects, for every point along the face sheets. The one-dimensional constitutive equation of SMA proposed by Brinson is employed. Equations of motion are derived using ...
