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.

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.

Stress Fields in Composite Laminates

International Journal of Solids and Structures, 1978
A new theory is proposed to define the complete stress field within an arbitrary composite laminate. The theory is based upon an extension of Reissner’s variational principle to laminated bodies. Weaknesses in previous laminate theories are discussed and it is demonstrated how these are overcome in the present formulation.

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.

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

Non-conventional Composite Laminates – Clutch Laminates

American Society for Composites 2017, 2017
This paper presents the design and manufacturing of novel non-conventional woven composite laminates coined as clutch laminates. Carbon/epoxy clutch laminates are manufactured using prepreg slit tape in an automated fiber placement (AFP) machine. The AFP process allows tailoring the material architecture resulting in innovative structures without the ...

Compression failure of composite laminates

2016
This chapter describes the application of a cohesive zone model to estimate the open-hole compressive (OHC) strength of composite laminates and to study the level-ply scaling effect on notch sensitivity. The modeling strategy is to replace the inelastic deformation associated with plasticity or microbuckling with a line crack and to assume some form of

INTELLIGENT TAILORING OF COMPOSITE LAMINATES

Carbon, 1989
Abstract A number of major failure modes in epoxy-matrix composites are reviewed including free edge opening mode delamination, free edge interlaminar shear controlled laminate failure, and impact damage. Methods for suppressing these failure modes through various laminate tailoring techniques are discussed.
