The application of the Dugdale model to an orthotropic plate
(Virginia Polytechnic Institute, 1968)
The Dugdale model is applied to an orthotropic plate. Stresses along the crack line and displacements along the crack and elastic plastic interface were found. The effect of orthotropy on several isotropic properties was ...
A study of biaxial viscoelastic behavior
(Virginia Polytechnic Institute, 1964)
An experimental study is made to investigate the feasibility of determining a viscoelastic stress-strain law for two (or three) dimensional stress conditions by means of one dimensional tests. The conclusions are based ...
Advances in displacement and strain analysis by moir{u00E9} interferometry
(Virginia Polytechnic Institute and State University, 1982)
Moiré interferometry was developed and extended in two related areas: (1) high density displacement fringes of excellent quality were obtained with a sensitivity of 97.6% of the theoretical maximum, and (2) the complete ...
A simplified method for the photoelastic determination of stress concentration factors in a tensile stress field
(Virginia Polytechnic Institute, 1962)
The stress concentration factors for rectangular slots with semicircular ends with their major axes inclined to the direction of a uniaxial tension field were investigated by photoelastic methods. A major portion of this ...
Slope deflection analysis of trussed rigid frames
(Virginia Polytechnic Institute, 1963)
A procedure for analyzing a two and three dimensional truss-rigid-frame with elope deflection method is investigated in this thesis.
In the first few chapters of this thesis the elope deflection equations for solving the ...
An analytic solution for the stress distribution in a semi- infinite strip loaded on the transverse edge
(Virginia Polytechnic Institute, 1966)
This thesis presents an analytic solution for the stress distribution in a semi-infinite strip subjected to symmetrical loads on the transverse edge. Three different types of loading on the transverse edge are considered: ...
Plane strain fracture toughness testing of hollow aluminum bars
(Virginia Polytechnic Institute and State University, 1970)
There are certain disadvantages to using round bars for plane strain fracture toughness testing. Specifically these are: (1) a large amount of material is required, for specimen fabrication, (2) a testing machine of great ...
Determination of stress intensity factors for cracks emanating from holes in finite thickness plates
(Virginia Tech, 1977-12-05)
<p>The stress freezing photoelastic method is a proven technique for the
estimation of stress intensity factors along crack fronts in complex three
dimensional problems. Comparisons between previous photoelastic and
approximate ...
Transient analysis of layered composite plates accounting for transverse shear strains and von Karman strains
(Virginia Polytechnic Institute and State University, 1982)
The increasing use of laminated composites in moving structures such as aircraft has led to a need for an efficient and accurate procedure for performing transient bending analysis of laminated composite plates. Classical ...
