A general process for optimization of a sandwich panel to minimize the effects of air blast loading is presented here. The panel geometry consists of two metal face plates with a crushable honeycomb or other type of core. Optimization is necessary as there is strong coupling between the several variables and the physics, which makes parametric studies relatively ineffective. Virtual testing is ...

Standard building practices commonly use gypsum-based drywall panels on the interior wall and ceiling applications as a partition to protect components of assembly from moisture fire uphold code ensure safety standards. Unfortunately, have poor resistance water are susceptible mold growth in humid climates. Furthermore, accumulation landfills can result toxic leachate impacting surrounding envi...

Metallic sandwich panels with textile cores have been analyzed subject to combined bending and shear and then designed for minimum weight. Basic results for the weight benefits relative to solid plates are presented, with emphasis on restricted optimizations that assure robustness (non-catastrophic failure) and acceptable thinness. Select numerical simulations are used to check the analytical r...

The current study presents a mathematical modeling for sandwich panels with foam filled orthogonally rib-stiffened core using Heaviside distribution functions. The governing equations of the static problem have been derived based on classical lamination theory. The present model contains three displacement variables considering all of the stiffness coefficients. A closed form solution using Gal...

Composites are nowadays increasingly used in industries such as aerospace, shipbuilding, automotive ... They are lightweight and have a very high specific stiffness, but defects such as delamination, inclusions may occur during their life cycle. Samples of sandwich honeycomb are tested using a 10 MHz central frequency phased array transducer constituted of 128 elements. Different defects are lo...

in this paper, the non-linear dynamic response of novel steel sandwich panel with hollow i-core subjected to blast loading was studied. special emphasis is placed on the evaluation of midpoint displacements and energy dissipation of the models. several parameters such as boundary conditions, strain rate, mesh dependency and asymmetrical loading are considered in this study. the material and geo...
