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> ...
Nonlinear oscillations under multifrequency parametric excitation
(Virginia Tech, 1988-11-05)
<p>A second-order system of differential equations containing a multifrequency parametric excitation and weak quadratic and cubic nonlinearities is investigated. The method of multiple scales is used to carry out a general ...
A finite element cure model and cure cycle optimization for composite structures
(Virginia Tech, 1987)
Stresses and deformations in cross-ply composite tubes subjected to circumferential temperature gradients
(Virginia Tech, 1985-07-05)
<p>The stresses and deformations in cross-ply composite tubes subjected in circumferential temperature gradients are studied. The motivation behind the study is the anticipated use of composite tubes in space structures ...

A study of vibrations in rotating laminated composite plates accounting for shear deformation and rotary inertia
(Virginia Tech, 1989-04-21)
A ftrst-order shear deformation plate theory is used to predict free vibration frequencies in rotating laminated composite plates. The theory accounts for geometric non-linearity in the form of von Karman strains. The plate ...
Nonlinear analysis of free-edge effects in laminated composites under axial loading
(Virginia Tech, 1987-05-05)
<p>A finite element model based on the quasi-three dimensional displacement field of Pipes and Pagano  with nonlinear strain-displacement relations is developed to study the free edge problem of composite laminates. ...
Long term behavior of Arall laminates
(Virginia Tech, 1988-06-05)
<p>The behavior of ARALL (ARamid ALuminum Laminates) subjected to tensionâ tension cyclic loading was experimentally investigated as a first step towards the understanding of the fatigue damage mechanisms in Arall ...
A beam test for adhesives
(Virginia Tech, 1988-07-15)
<p>The strength of materials solution for a new bonded cantilever beam test specimen to determine adhesive shear properties is reviewed and discussed. A parametric analysis for the adhesive shear stress and for the end ...
