Feasibility of fiber reinforced composite materials used in highway bridge superstructures
(Virginia Tech, 1988-12-05)
<p>Composite materials are considered here as structural materials of highway bridge superstructures. Bridge deck designs can be done according to <i>AASHTO</i><sup>1</sup> specification and elastic design concepts. </p><p> ...
Indentation testing of composite materials: a novel approach to measuring interfacial characteristics and engineering properties
(Virginia Tech, 1991-03-05)
Findings made through the indentation testing of composites are presented in this thesis. The concept was developed as an attempt to evaluate the interfacial shear strength at a mesolevel, possibly overcoming the deficiencies ...
Variable complexity modeling of postbuckled stiffeners for delamination initiation
(Virginia Tech, 1993-06-18)
Delamination at the free edge is analyzed as a mode of failure for uniaxial compression of postbuckled structural components. Analyses are performed for I-section stiffeners and for a dropped-ply laminate, all of which ...
Effect of fiber morphology on composite properties
(Virginia Tech, 1988-05-05)
</p>The effect of the cylindrically orthotropic morphology known to exist in graphite fibers on the effective properties of a composite material was studied using the composite cylinder assemblage model. The cylindrical ...

Nondestructive evaluation of complex geometry advanced material components
(Virginia Tech, 1989-03-01)
The potential of many nondestructive inspection methods and evaluation procedures are often demonstrated under rather pristine conditions. Considerable difficulty may result from attempting to apply such methodologies to ...
An acousto-ultrasonic system for the evaluation of composite materials
(Virginia Polytechnic Institute and State University, 1986)
A presentation is given of an acousto-ultrasonic system for the evaluation of composite materials. First, a brief statement will be made on the acousto-ultrasonic technique and its relative worth compared to other ...
Delamination buckling, postbuckling, and growth in axially loaded beam-plates
(Virginia Polytechnic Institute and State University, 1987)
The purpose of this study is to develop a simple one-dimensional model to analyze axially loaded beam-plates containing cracks which extend through the thickness of the beam-plates. Although the material analyzed is ...
