The method adopted relies on the index theory for laminations, and the main tools are the Connes Skandalis longitudinal K-theory index morphism together with the measured index formula.
Take them to a professional print shop and ask for rigid lamination on black paper and opt for a felt backing.
The first to lapse will be patent 4,629,657 for a "biaxially oriented polypropylene film construction for special lamination," which was granted in 1986 and will expire in 2004.
Typical numerical results for second-order statistics of linear free vibration response of simply supported laminated composite conical shells are obtained for different lamination schemes and thickness to radius ratios.
In general, therefore, for a lamination scheme of realistic structures in composite materials, a symmetric laminate is preferred to minimize influence from coupling of stiffness terms.
The effectiveness of the models is indicated by making numerical comparisons with the exact three-dimensional theory of the elasticity for several lamination schemes, angle/cross-ply lay-ups, and characteristic geometric ratios for low and higher frequencies.
Section 6 considers one particular device construction: A foil that is suitable for glass lamination and which, in the author's view, holds particular promise for low-cost large-area implementation of EC smart windows.
Results are tabulated for different lamination schemes and compared to available studies in the literature.
New results for different lamination schemes with elastically restrained edges are presented, which may serve as benchmark solutions.
Computed results for different lamination schemes are found to match well with those obtained by other researchers.
