In the present work a non-linear dynamic response of a continuous sandwich beam with SMA hybrid composite face sheets and flexible core is analyzed taking into account the phase transformation and also the material non-linearity effects, for every point along the face sheets. The one-dimensional constitutive equation of SMA proposed by Brinson is employed. Equations of motion are derived using ...

This thesis investigates the mechanical behavior of a new type of formable all-metal bi-directionally corrugated sandwich sheet material. Unlike conventional flat sandwich panel materials, this type of sandwich sheet material can be formed into three-dimensional shapes using traditional sheet metal forming techniques. In a first step, the core structure geometry is optimized such as to offer th...

USC’s work on sandwich structure acoustics began in 1998 and has evolved in close collaboration with the M.C. Gill Corporation, a leading manufacturer of sandwich panels for aircraft interiors. The work has had both an applied mission and an academic focus, and presents an example of university-industry collaboration can produce mutual benefit while advancing scientific understanding. Here, we ...

We observe that ω(G) + χ(S( G)) = n = ω(S( G)) + χ(G) for any graph G with n vertices, where G is any acyclic orientation of G and where S( G) is the (complement of the) auxiliary line graph introduced in [1]. (Where as usual, ω and χ denote the clique number and the chromatic number.) It follows that, for any graph parameter β(G) sandwiched between ω(G) and χ(G), then Φβ( G) := n−β(S( G)) is s...

Bárány, Hubard, and Jerónimo recently showed that for given wellseparated convex bodies S1, . . . , Sd in R and constants βi ∈ [0,1], there exists a unique hyperplane h with the property that Vol(h+ ∩ Si) = βi · Vol(Si); h+ is the closed positive transversal halfspace of h, and h is a “generalized ham-sandwich cut.” We give a discrete analogue for a set S of n points in R which are partitioned ...

Nanoscale antennas sandwiched between two graphene monolayers yield a photodetector that efficiently converts visible and near-infrared photons into electrons with an 800% enhancement of the photocurrent relative to the antennaless graphene device. The antenna contributes to the photocurrent in two ways: by the transfer of hot electrons generated in the antenna structure upon plasmon decay, as ...

Previous reports have indicated that in vitro biliary clearance (Cl(biliary)) determined in sandwich-cultured hepatocytes correlates well with in vivo Cl(biliary) for limited sets of compounds. The purpose of this study was 1) to determine the in vitro Cl(biliary) in sandwich-cultured human hepatocytes of angiotensin II receptor blockers and HMG-CoA reductase inhibitors that undergo limited met...
