Developments in the study of logical limit laws for both labelled and unlabelled structures, based on the methods of Compton (1987/1989), are surveyed, and a sandwich theorem is proved for multiplicative systems.

Fatty acid modified Mn(12) derivatives can self-assembly into vesicular structures in organic media. The vesicular assemblies have a sandwich structure with Mn(12) cluster separated by two alkyl chain layers.

A study of the application of two full field optical strain analysis techniques to aircraft standard carbon fibre composites is carried out. The goal of the work is to assess the feasibility of using the techniques on full scale tests of secondary sandwich structure aircraft panels. The work concentrates on two techniques: Digital Image Correlation (DIC) and Thermoelastic Stress Analysis (TSA)....

Metallic sandwich panels with periodic, open-cell cores are important new structures, enabled by novel fabrication and topology design tools. Fabrication protocols based on the sheet forming of trusses and shell elements (egg-boxes) as well as textile assembly have allowed the manufacture of robust structures by inexpensive routes. Topology optimization enables control of failure mechanisms at ...

Recent developments on the optimization and parameter estimation in hybrid active-passive composite sandwich structures are presented. For this purpose, a mixed layerwise finite element model has been formulated, by considering a higher order shear deformation theory to represent the displacement field in the viscoelastic core and a first order theory for the displacement fields of the adjacent...
