... sensors to monitor the performance of the structures. In this study, the smart composite sandwich structure (CSS) samples are fabricated with glass microballoons syntactic foam core and resin infused glass-fiber face skins (with piezoelectric fiber composite sensors (PFCS) embedded inside the resin...

...Sameer L. Peter; Eyassu Woldesenbet The effect of nanoclay on the high strain rate mechanical properties of syntactic foams is studied. Two types of microballoons with different wall thicknesses are used in fabrication of plain and nanoclay syntactic foams. Plain syntactic foams are fabricated...

..., it appears interesting to investigate a process like chip formation, where both plasticity and fracture intervene. Finite element simulations of such a process are performed using an elastoplastic constitutive model for isotropic foams to describe the material, and a cohesive zone model to describe the crack...

...Chris Barlow; Vipin Kumar; Brian Flinn; Rajendra K. Bordia; John Weller The effect of density (relative densities 0.33 to 0.90) on the impact behavior of microcellular polycarbonate (PC) was investigated. Cell size and foaming gas content were also considered. Flexed-beam Izod impact tests were...

...Y. Wang; G. Gioia; A. M. Cuitin˜o Compressed open-cell solid foams frequently exhibit spatially inhomogeneous distributions of local stretch. The theoretical aspects of this deformation habit have not been clearly elucidated. Here we briefly discuss the energetics of the problem to show...

...N. J. Mills; A. Gilchrist The high strain tensile deformation of open-cell foams is analyzed, using a Kelvin foam lattice model. The stretching, bending, and twisting of elastic cell edges is analyzed, and the deformed cell shapes predicted. The stress-strain relation and Poisson’s ratio...
