Deflection and Free Vibration of Sandwich Panel with Honeycomb Core on Winkler Elastic Foundation
In this paper deflection and free vibration of sandwich panel is studied. The core of Sandwich panels is made of hexagonal honeycomb and faces are made of two different materials of Carbon Fiber Reinforced Plastic and K-aryl/epoxy covering. The governing equations are deduced from the First order Sheer Deformation Theory (FSDT) and they are solved using Generalized Differential Quadrature Metho...
متن کاملDynamic Analysis of Geometrically Nonlinear Circular Plates on Winkler Foundation
Geometrically nonlinear analysis of thin circular plates on Winkler elastic foundations has been studied in this paper. The nonlinear partial differential equations obtained from von Karman’s large deflection plate theory have been solved by using the discrete singular convolution (DSC) in the space domain and the harmonic differential quadrature (HDQ) method in the time domain.

متن کاملInfluence of reinforcement arrangement in flexural fire behavior of hollow core slabs
This paper describes four standard scale fire tests conducted on precast prestressed hollow core slabs under flexure. The influence of the reinforcement arrangement was investigated using two test parameters: the average axis distance (from 30.1 to 46.7 mm), and the type of reinforcement (5 mm diameter wires and 9.5mm diameter strands). An ISO 834 standard fire was applied maintaining the load ...
متن کاملHollow Core ?
We carried out the Gaussian fitting to the profile of PSR B1237+25 and found that six components rather than five are necessary to make a good fit. In the central part, we found that the core emission is not filled pencil beam but is a small hollow cone. This implies that the impact angle could be β < 0.5 •. The " hollow core " is in agreement with Inverse Compton Scattering model of radio puls...
