Semi-active structural control systems with nonlinear actuator dynamics: Design, stability analysis, and experimental verification.
(2001)
The dissertation presents the development and experimental validation of control laws that provide stable closed-loop behavior and good performance for semi-active control systems with nonlinear actuator dynamics. In ...
Analysis and control of thermoelastic vibrations in plate structures.
(2001)
This work is concerned with the analysis and control of thermoelastic vibrations in rectangular plate structures using piezoelectric materials for the sensor(s) and actuator(s). Both isotropic and symmetrically laminated, ...
Internet-based distributed collaborative environment for engineering education and design.
(2001)
The concept of collaborative design and analysis using the Internet was investigated and implemented. Geographically dispersed users can build the same geometric model simultaneously over the Internet and communicate with ...
Multidisciplinary design optimization of a fighter aircraft with damage tolerance constraints and a probabilistic model of the fatigue environment.
(2001)
Damage tolerance analysis (DTA) was considered in the global design optimization of an aircraft wing structure. Residual strength and fatigue life requirements, based on the damage tolerance philosophy, were investigated ...
Computer-integrated finite element modeling and simulation of human middle ear.
(2001)
The work reported in this dissertation is the result of a joint venture of biomedical scientists and engineers for understanding human middle ear mechanics through finite element modeling and analysis. The main objective ...
Instability analysis of a low-density gas jet injected into a high-density gas.
(2001)
The objective of this study was to determine the effects of buoyancy on the absolute instability of low-density gas jets injected into high-density gas mediums. Most of the existing analyses of low-density gas jets injected ...
