Hydrophilic Support Films of Controlled Thickness and Composition

Review of Scientific Instruments, 1973
A method is described for producing thin, hydrophilic support films for electron microscopy. These films have a well defined composition and can be made as thin as 10–15 Å. An application is described in which these hydrophilic films are used as ultrathin ``windows'' for frozen, aqueous specimens.

Simple thickness modes for laminated composite materials

Journal of Sound and Vibration, 1972
The simple thickness modes for laminated media with layering both parallel and perpendicular to the plate-free surfaces are studied according to the “effective stiffness” theory and the results obtained are compared with results found from the effective modulus” theory.

Temperature distribution of thick thermoset composites

Modelling and Simulation in Materials Science and Engineering, 2004
The development of temperature distribution of thick polymeric matrix laminates during an autoclave vacuum bag process was measured and compared with numerically calculated results. The finite element formulation of the transient heat transfer problem was carried out for polymeric matrix composite materials from the heat transfer differential equations

Curing simulation of thick thermosetting composites

Composites Manufacturing, 1994
Abstract A one-dimensional through-the-thickness simulation is developed in which heat conduction, kinetic, viscosity and flow (squeezed sponge model) equations are solved as a coupled system of equations. The control-volume method combined with the alternating direction explicit method is employed in the solution.

Vibration of Homogeneous and Composite Thick Barrel Shells

Journal of Vibration and Control, 2004
This paper presents a vibration analysis for homogeneous and laminated composite deep, thick barrel shells using recently derived equations of elastic deformation. Assuming a first-order linear displacement field, the equations include accurate force and moment resultants, in which the stresses over the thickness of the shell are integrated exactly on ...
