Intelligent Processing of Thick Composites

1999
Abstract : Composites consolidation In various manufacturing processes has been studied from a unified point of view to develop a simulation model. As a result a master formulation is now available and can be tailored to each manufacturing process.

Fracture of thick laminated composites

Experimental Mechanics, 1986
The fracture of thick laminated graphite/epoxy composites has been the subject of an extensive research program. The program was divided into three major areas of investigation which included laminate thickness, laminate stacking sequence, and part-through surface flaws.

Localization of Ultrasound in Thick Composites

1990
The propagation of ultrasound in fiber-reinforced composites is controlled by the relative magnitudes of characteristic length variables. These length variables are the wavelength (Λ), the fiber diameter (a), the thicknesses of plies (h), and the overall thickness of the component (H).

Design of Thick Composite Cylinders

Journal of Pressure Vessel Technology, 1988
A simple and efficient design method for thick composite cylinders is presented. Micromechanics and macromechanics are integrated by simple relations and the integrated micro and macromechanics approach has been adopted to enable the designers to instantly study the sensitivity of the micromechanical variables on the final design.

Leaf thickness and carbon isotope composition in the Crassulaceae

Oecologia, 1981
Measurements of leaf thickness and δ13C value were obtained for twenty species and three intergeneric hybrids of the Crassulaceae. The data include plants growing in their native habitats and also in greenhouse cultivation. There is a strong relationship between leaf thickness and leaf δ13C values. The plants with the thickest leaves of ca.

Measurement of thickness and composition of a solvent film on a bubble

Journal of Colloid and Interface Science, 2006
Solvent-coated air bubbles in the air-assisted solvent extraction (AASX) process achieve the dual role of high solvent specific surface area and ease of phase separation. The properties and thickness of the solvent film control the process. As an approach to the study, the layer interferometry (in the UV-vis region) and FT-IR spectroscopy were used to ...

Thick Composite Plates Subjected to Lateral Loading

Journal of Applied Mechanics, 1987
An analytical solution for an orthotropic plate subjected to general lateral loading is presented. The solution uses a stress function approach to obtain the localized stresses and strains due to the loading by an axisymmetric rigid sphere. Plots of load versus local indentation are compared with experimental test data previously reported in the ...

Composite plates of variable thickness

Journal of Machinery Manufacture and Reliability, 2010
A three-dimensional static model of an elastic-plastic body is considered with accounting for the dependence of the material characteristics on the temperature. The influence of the minimal and maximal plate thicknesses and the heat source power on the bending value and temperature is studied in order to reveal the cases of heating when in the ...

Heterogeneity of the composition and thickness of tracheal mucus in rats

American Journal of Physiology-Lung Cellular and Molecular Physiology, 1997
Inability to preserve airway mucus in situ has limited our understanding of its structure and function. This light- and transmission electron-microscopic study of rat tracheal mucus used a nonaqueous fixative that retains mucus (epiphase) over a lucent layer (hypophase).

Buckling Optimization of Composite Columns with Variable Thickness

Journal of Reinforced Plastics and Composites, 2007
A novel approach to the optimization of flexible columns against buckling is presented. The problem of determining the shape of the column that has possibly the largest critical buckling load of columns of a given length and volume is solved for composite materials.
