A comparison of displacement and hybrid stress models for two dimensional finite element analysis
(Virginia Polytechnic Institute and State University, 1987)
An eight-node isoparametric hybrid stress element is developed for two dimensional plane stress and plane strain analyses. The assumed stresses are represented by 18 unknown parameters. An eight-node isoparametric displacement ...
A finite element study of bending stress variation in meshed spur gear pairs
(Virginia Polytechnic Institute and State University, 1987)
A study of the bending stresses in a pair of meshed spur gears using the finite element method is presented. The models analyzed were in the shape of a circular gear with five teeth or a five-tooth rack. A unit torque (1 ...
Vibrations of an isolated wind turbine blade using the finite element method
(Virginia Polytechnic Institute and State University, 1986)
The finite element method is applied to an isolated and twisted wind turbine blade which is rotating in a vertical plane to determine its structural dynamic characteristics. The equations of motion are formulated for a ...
Synthesis of a near-optimum finite element mesh
(Virginia Polytechnic Institute and State University, 1982)
A finite element program post-processor is developed to help synthesize a near-optimum mesh. This post-processor displays, interactively, six different energy functions, along with the usual stress functions. The six energy ...
Effect of in situ stresses on the stress analysis in soils by the finite element method
(Virginia Polytechnic Institute and State University, 1982)
The effect of in situ stresses on the stresses and displacements in soils was investigated by the finite element method. The soil was considered as a nonlinear elastic media having a hyperbolic stress strain relationship. ...
Edge caps for reinforcing composite laminates
(Virginia Polytechnic Institute and State University, 1985)
A method for reinforcing the free edges of a symmetric 11-ply graphite-epoxy laminate by adding a one-layer Kevlar-epoxy edge cap is studied. Generalized plane strain finite element analysis is used to predict that ...
Elastic-plastic finite element modeling of long span composite joists with incomplete interaction
(Virginia Tech, 1992)
This thesis presents elastic-plastic finite element analyses of seven long span composite open-web steel joists. These analyses account for the incomplete interaction between the concrete slab and the steel joist by modeling ...
Analytical investigation of composite diaphragms strength and behavior
(Virginia Tech, 1993)
Composite diaphragm strength and behavior were studied using non-linear finite element analysis. A total of 57 three panel diaphragm models were analyzed to failure.
Parameters studied included beam size and orientation, ...
Non-linear finite element analysis of steel plate tension members
(Virginia Tech, 1992)
In the American Institute of Steel Construction (AISC) LRFD specification, the shear lag coefficient for plate members is dependent on only the ratio of the welding length to the plate width. To determine how this ratio ...
Finite element modeling of a refrigeration compressor for noise prediction applications
(Virginia Tech, 1993)
The study involves the development of a finite element model of a hermetic reciprocating compressor for noise prediction applications. Inherent difficulties in developing the finite element model of a complicated structure ...
