    Finite Element Modeling of Tow-Placed Variable-Stiffness Composite Laminates 

    Langley, Patrick Tyler (Virginia Tech, 1999-05-26)
    Tow-placement machines have made it possible to manufacture curved-fiber composite tow paths. A composite structure with curved-fiber tow paths can be formed in a manner similar to filament winding. The result is a laminate ...

    Parameter Identification of Nonlinear Systems Using Perturbation Methods and Higher-Order Statistics 

    Fung, Jimmy Jr. (Virginia Tech, 1998-08-03)
    A parametric identification procedure is proposed that combines the method of multiple scales and higher-order statistics to efficiently and accurately model nonlinear systems. A theoretical background for the method ...

    Nonlinear transverse vibrations of centrally clamped rotating circular disks 

    Manzione, Piergiuseppe (Virginia Tech, 1999-03-02)
    A study is presented of the instability mechanisms of a damped axisymmetric circular disk of uniform thickness rotating about its axis with constant angular velocity and subjected to various transverse space-fixed loading ...

    Characterization and Modeling of a Fiber-Reinforced Polymeric Composite Structural Beam and Bridge Structure for Use in the Tom's Creek Bridge Rehabilitation Project 

    Hayes, Michael David (Virginia Tech, 1998-12-12)
    <p> Fiber reinforced polymeric (FRP) composite materials are beginning to find use in construction and infrastructure applications. Composite members may potentially provide more durable replacements for steel and concrete ...

    An acousto-ultrasonic system for the evaluation of composite materials 

    Kiernan, Michael T. (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 ...

    Energy Absorption Capacity of Graphite-Epoxy Composite Tubes 

    Schultz, Marc Robert (Virginia Tech, 1998-11-11)
    The energy absorption capacity of a series of axially crushed composite tubes fabricated from high tow count graphite fiber is compared with those of similar tubes fabricated from aerospace-grade fiber to determine the ...

    The nonlinear viscoelastic behavior of adhesives and chopped fiber composites 

    Cartner, James Smoot (Virginia Polytechnic Institute and State University, 1978)
    The viscoelastic behavior of a chopped glass fiber/polyester sheet molding compound (SMC-25) and of a modified epoxy adhesive (Metlbond 1113-2) as determined by creep and creep recovery tests is presented. A nonlinear ...

    Effect of Material and Geometric Parameters on Deformations of a Dynamically loaded Prenotched Plate 

    Gummalla, Rakesh R. (Virginia Tech, 1998-09-18)
    We analyze plane strain thermomechanical deformations of a prenotched rectangular plate impacted on one side by a prismatic body of rectangular cross-section and moving parallel to axis of the notch. Both the plate and the ...

    Acousto-Ultrasonic Evaluation of Cyclic Fatigue of Spot Welded Structures 

    Gero, Brian Matthew III (Virginia Tech, 1997-08-28)
    An acousto-ultrasonic approach is used to explore the damage development in tensile shear spot welds during fatigue loading. There is reasonable data to support the hypothesis that a decrease in an AU signal is indicative ...

    Experimental analysis of a haunched, skewed, reinforced concrete, rigid-frame bridge model 

    Pap, Arpad A. (Virginia Polytechnic Institute, 1959)
    A one-tenth scale model of a skewed reinforced concrete rigid frame bridge was constructed and tested both within the elastic range and to ultimate load. The model was fabricated of reinforced concrete using a 1: 3.8 : 0 ...
