Application of distributed measurements for finite element model verification
(Virginia Tech, 1992-05-05)
<p>The wealth of experimental laser data and its high accuracy allow a rigorous
comparison between a distributed model and distributed measurements that was not
possible previously. The purpose of this work is to obtain ...
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 ...
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 ...
Thermal-magnetic finite element model of a high frequency transformer
(Virginia Tech, 1989-11-30)
<p>In high-frequency power transformers, magnetic material properties cannot be assumed to be constant. These properties vary with frequency, temperature, and magnetic flux density. Heat generation is, in turn, a function ...
A two-dimensional finite element mesh generator with automatic transitioning capability
(Virginia Polytechnic Institute and State University, 1982)
A simple, user friendly, mesh generator designed as a preprocessor for two-dimensional finite element codes is presented. The program generates both triangular and quadrilateral two-dimensional elements and has automatic ...
Plane frame element addition to the MESS finite element program
(Virginia Polytechnic Institute and State University, 1985)
A plane frame element based on linear, elastic theory is developed and implemented into the MESS finite element program. Post-processed results include nodal displacements, end reactions, maximum tensile and average shear ...
Static and free vibration analysis of advanced composites using shear-deformable rectangular plate finite elements
(Virginia Polytechnic Institute and State University, 1988)
A comparison of rectangular finite elements based on a first order shear deformation plate theory and a refined higher order plate theory is presented. Special attention is given to the representation of transverse shear ...
A finite element analysis and redesign of the draftsill casting on a railroad hopper car
(Virginia Polytechnic Institute and State University, 1987)
This paper presents a static three-dimensional finite element analysis and redesign of a railroad hopper car draftsill. The purpose of the work was to modify the current draftsill structure to minimize its weight without ...
Investigation of the finite element method for computing wheel/rail contact forces in steady curving
(Virginia Polytechnic Institute and State University, 1987)
The understanding of rail vehicle steady-state and dynamic curving has increased
substantially in the last few years. Contemporary curving models include such nonlinear
effects as two-point contact, creep force saturation, ...
A finite element analysis of pinion shaped spur gear teeth
(Virginia Polytechnic Institute and State University, 1984)
An analysis of the effects of gear shaping with a pinion cutter upon the geometry and root stresses in external spur gears using the finite element method is given. The models analyzed have the shape of a ring with three ...
