Sandwich structures are very attractive due to their high strength at a minimum weight, and, therefore, there has been a rapid increase in their applications. Nevertheless, these structures may present imperfect bonding or debonding between the skins and core as a result of manufacturing defects or impact loads, degrading their mechanical properties. To improve both the safety and functionality...

An experimental and computational study of the bending response of steel sandwich panels with corrugated cores in both transverse and longitudinal loading orientations has been performed. Panel designs were chosen on the basis of failure mechanism maps, constructed using analytic models for failure initiation. The assessment affirms that the analytic models provide accurate predictions when fai...

Abstract When subjected to bending loads, sandwich panels are highly efficient structural components with the potential achieve substantial weight reduction. A successful design methodology for should aim at maximising this reduction while considering various possible failure mode in a simple yet accurate manner. This paper investigates application of steel as two-way deck systems. Near-optimal...

The mechanical properties of certain flexible core materials ship structure sandwich panels, having skins made metallic or composite laminates maybe significantly influenced by the temperature variations that may occur during operational loading. At same time, improving knowledge behaviour these panels in terms bending strength and other stress/strain related aspects various harsh conditions in...

This numerical study compares single-phase forced convective heat transfer between two sandwich panels with tetrahedral metallic lattice cores separately fabricated by investment casting and the more cost-effective metal sheet folding method. The numerical model is validated against available experimental data. For a given Reynolds number and core porosity, the results reveal that the brazed sa...
