Finishing of Composites and Laminates

Dental Clinics of North America, 1989
Regardless of the color, shape or attention to detail, there must be sufficient time to adequately finish all restorations. Both esthetics and function can best be satisfied when the restoration acquires its maximal finish. In the final analysis, not only will the restoration look better, but it will look better for a longer period of time.

A laminate theory of piezoresistance for composite laminates

Composites Science and Technology, 1999
Electric conductivity, piezoresistivity and piezoconductivity of orthotropic materials are studied theoretically on the basis of electrostatic theory and the classical thin laminate theory. The correlation between piezoresistivity and piezoconductivity in the Cauchy strain is derived.

Nonlinear Deformation of Laminated Composites

Journal of Engineering Mechanics, 1989
A method is presented for the nonlinear analysis of an element of a laminated composite using the Ramberg‐Osgood stress‐strain relation and considering transverse shear, degradation of elastic moduli due to fracture, and deformation theory of plasticity generalized for anisotropic inelastic material.

Composite Laminate Stiffnesses and Their Sensitivities

20th Design Automation Conference: Volume 2 — Robust Design Applications; Decomposition and Design Optimization; Optimization Tools and Applications, 1994
Abstract The great number of possible stacking orders to form laminates suggests to apply optimization, more frequently than usual, in the design of structures made of composite materials. One of the columns upon which optimization of structures is built is the mathematical search procedure for locating a minimum (or maximum) of a ...

Dynamic characteristics of composite laminates

Journal of Sound and Vibration, 1972
An exact solution for the vibration of elastic composite laminates in cylindrical bending is presented. Dispersion curves for multi-layer symmetrical and unsymmetrical laminates with materials possessing high and low degrees of anisotropy at various fiber orientations are compared with those obtained from an approximate shear deformation theory.

POSTBUCKLING OF LAMINATED COMPOSITES WITH DELAMINATIONS

34th Structures, Structural Dynamics and Materials Conference, 1993
Summary: Postbuckling analysis of laminated composites with delaminations is presented. A finite element method based on a layerwise laminated composite plate theory is developed to formulate and solve the problem. Geometric nonlinearity in the sense of von Kármán and imperfections in the form of initial global deflection and initial delamination ...

Acoustic Emission in Composite Laminates

Journal of Nondestructive Evaluation, 1998
The response of a laminated plate to internal acoustic emission events is examined in detail. The plate consists of four layers of a unidirectional fiber composite material arranged in a cross-ply configuration. The sources considered include a vertical line couple, a horizontal line couple and a line double couple without moment.

Thermal Response in Laminated Composites

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1975
AbstractA semi‐infinite laminated composite in which the matrix and filler material are aligned parallel to the heat propagation direction is considered. At x = 0, there is applied a harmonic boundary heat flux of y‐periodicity conforming to the periodicity of the layered composite. The Fourier integral solution is decomposed into normal modes.

Laminate theory: macroanalyses of composite laminates

1993
It has been shown in chapter 2 that composite materials are manufactured as laminates, consequently in analysing the lamina, the primary aim is to obtain predictions of the average behaviour of the composite from the properties of the components. From the point of view of the mechanical properties of the composite lamina, the area of interest to the ...

Strength of composites repaired by laminating with dissimilar composites

The Journal of Prosthetic Dentistry, 1988
D efective composite restorations are usually replaced by completely removing the existing material. However, certain clinical conditions may make it advisable to remove only a portion of the existing restoration before the addition of new material. For example, this technique might be preferred if the existing restoration is near the pulp, retained by
