Sustainable sandwich composite structures made from aluminium sheets and disposed bottle caps

Guided waves propagating in sandwich structures made of anisotropic, viscoelastic, composite materials.

The propagation of Lamb-like waves in sandwich plates made of anisotropic and viscoelastic material layers is studied. A semi-analytical model is described and used for predicting the dispersion curves (phase velocity, energy velocity, and complex wave-number) and the through-thickness distribution fields (displacement, stress, and energy flow). Guided modes propagating along a test-sandwich pl...

Force protection using composite sandwich structures

In the recent past, advances have been made in the attempt to utilize composite materials as components in protective structures such as those employed by the Air Force to secure critical military assets. In such applications, where lightweight materials that exhibit large levels of energy absorption and high strength/stiffness characteristics are desirable, composite sandwich constructions off...

Damage tolerance and residual strength of composite sandwich structures

Structural-Acoustic Optimization of Composite Sandwich Structures: A Review

We review recent advances in the area of composite sandwich modeling, sensitivity analyses, optimization techniques and applications, with the focus on structuralacoustic problems. The optimization of sandwich structures is with respect to passive design parameters, such as material constants, geometric parameters, cellular core geometry and boundary conditions.

Analysis of Viscoelastic Functionally Graded Sandwich Plates with CNT Reinforced Composite Face Sheets on Viscoelastic Foundation

In this article, bending, buckling, and free vibration of viscoelastic sandwich plate with carbon nanotubes reinforced composite facesheets and an isotropic homogeneous core on viscoelastic foundation are presented using a new first order shear deformation theory. According to this theory, the number of unknown’s parameters and governing equations are reduced and also the using of shear correct...
