Fourteen composite honeycomb sandwich panels were tested to failure under compressive loading. The test specimens included panels with both eight and twenty-four ply graphite-bismaleimide composite facesheets and both titanium and graphite-polyimide core materials. The panels were designed to have the load introduced through fasteners attached to pairs of steel angles on the ends of the panels ...

The study aimed to determine the effect of impregnation with modified starch recycled paper (Testliner) on elasticity constants slender core cells and influence strength honeycomb facings made thin particleboards. experimental tests were carried out beams subjected three-point bending. It was shown that hexagonal significantly differentiate their elastic properties panels in main directions ort...

Honeycomb sandwich panels can reduce weight, and particular strength needs are crucial to the modern aerospace industry. The principal benefits of honeycomb include rigidity, stress absorption, fatigue resistance, resistance weather, chemicals, fire isolation. Today, choosing a design with cheap recyclable core material is common due mechanical acoustic requirements high weight target. Aeroplan...

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...

Punching experiments on wide honeycomb sandwich beams were performed to evaluate the predictive capabilities of a newly developed constitutive model in structural applications. The employed constitutive model for plastically com-pressible orthotropic materials accounts for both non-uniform hardening and softening associated with stressing in different directions. This feature is vital when asse...

Low weight and high load capacity are remarkable advantages of sandwich panels with corrugated core, which make them more considerable by engineering structure designers. It’s important to consider the limitations such as yielding and buckling as design constraints for optimal design of these panels. In this paper, multi-objective optimization of sandwich panels with corrugated core is carried ...
