Finite element analysis of geodesically stiffened cylindrical composite shells using a layerwise theory
(Virginia Tech, 1994-06-01)
Layerwise finite element analyses of geodesically stiffened cylindrical shells are presented In this work. The layerwise laminate theory of Reddy (LWTR) is developed and adapted to circular cylindrical shells. The Ritz ...
Stochastic and seismic design response of linear and nonlinear structures
(Virginia Tech, 1992)
New methods for calculating the stochastic and seismic design response of linear and nonlinear structures are presented. For linear structures, two approaches are developed: (1) the modified mode displacement approach ...
Deformations of Piezoceramic-Composite Actuators
(Virginia Tech, 1999-11-11)
In the past few years a new class of layered piezoceramic and piezoceramic-composite actuators, known as RAINBOW and GRAPHBOW, respectively, that are capable of achieving 100 times greater out-of-plane displacements than ...
The Development and Control of Axial Vortices over Swept Wings
(Virginia Tech, 1999-08-02)
The natural unsteadiness in the post-breakdown flowfield of a 75Â° sweep delta wing at 40Â° angle of attack was studied with dual and single point hot-wire anemometry in the Engineering Science and Mechanics (ESM) Wind ...
Viscous-inviscid interactions of dense gases
(Virginia Tech, 1994)
Crack Path Selection in Adhesively Bonded Joints
(Virginia Tech, 1999-11-15)
This dissertation is to obtain an overall understanding of the crack path selection in adhesively bonded joints. Using Dow Chemical epoxy resin DER 331Â® with various levels of rubber concentration as an adhesive, and ...
Modeling and response analysis of thin-walled beam structures constructed of advanced composite materials
(Virginia Tech, 1990)
Thin-walled beam structures are adopted as structural members in various fields of modem technology including aeronautical/aerospacial, naval, mechanical and civil ones. With the advent of advanced composite material ...
Analysis and Design of Variable Stiffness Composite Cylinders
(Virginia Tech, 1998-10-13)
An investigation of the possible performance improvements of thin circular cylindrical shells through the use of the variable stiffness concept is presented. The variable stiffness concept implies that the stiffness ...
Stress and reliability analysis of multilayered composite cylinder under thermal and mechanical loads
(Virginia Polytechnic Institute and State University, 1992)
An analysis of interlaminar stresses in unsymmetrically laminated plates
(Virginia Tech, 1990)
