Sandwich structures benefit from the geometrical stiffening effect due to their high cross-sectional area moment of inertia. Transferred carbon fiber-reinforced plastic (CFRP) components, needed amount fiber (CF) material can be reduced and with it CO2 footprint. The combination a light foam core continuous face sheets is suitable for lightweight design. Traditionally, CFRP sandwich are manufac...

In this study, a sandwich beam with periodic multiple dissipative resonators in the sandwich core material is investigated for broadband wave mitigation and/or absorption. An analytical approach based on the transfer matrix method and Bloch theorem is developed for both infinite and finite sandwich structures. Wave attenuation constants are theoretically obtained to examine the effects of vario...

in the current study, the effects of interactions of the moving loads and the attached mass-spring-damper systems of the composite plates on the resulting dynamic responses are investigated comprehensively, for the first time, using the classical plate theory. the solution of the coupled governing system of equations is accomplished through tracing the spatial variations using a navier-type sol...

With the continuous improvement of building energy-conservation requirements, both traditional concrete external insulation and internal have been unable to meet energy-saving needs. In order demands in new era, precast external-wall-insulation technology should be developed. this study, a bending static test numerical simulation were carried out evaluate influence thickness inner wythe length ...

In order to study the anti-penetration performance of corrugated plate/aluminum foam composite sandwich structure, LS-DYNA software was used simulate. The penetration model 7.62 mm rifle bullet into structure established, and residual velocities bullets at five positions were compared analyzed. influence different initial velocity forward 900m/s angle on B is focused. results show that position...

Laminated composite plates are widely used in modern structures. Resins of composites are almost made of polymers which show time dependent and and in some cases stress dependent behaviour. In this paper, a laminated composite plate is analysed using a multiscale method. At first, material properties of a lamina is obtained using an analytical micromechanical approach called simplified unit cel...

BACKGROUND The UK Eatwell Plate is consumer based advice recommending the proportions of five food groups for a balanced diet: starchy foods, fruit and vegetables, dairy foods, nondairy sources of protein and foods and drinks high in fat or sugar. Many foods comprise ingredients from several food groups and consumers need to consider how these fit with the proportions of the Eatwell Plate. This...

The use of composite laminate materials has increased rapidly in recent years due to their excellent strength to weight ratio and resistance to corrosion. In the construction of marine vessels, stiffened plates are the most commonly used structural elements, forming the deck, bottom hull, side shells and bulkheads. This paper presents the use of a stochastic approach to the design of stiffened ...
