AE 498 ASS: Advanced Aerospace Structures (Fall 2008)
This course builds on the students’ background on thin walled structures (AE322) to address elastic thin plate and shell structures with applications to aerospace industry. The course includes boundary value problems with circular and rectangular plates, combined lateral and in-plane loading, elastic buckling of plates, energy methods, large deflections in plates, thermal stresses, membrane and bending stresses in shells, applications to circular and spherical structures, and cylindrical shells under general loading.
AE 598: Contact Mechanics and Methods in Scanning Probe Microscopy (Fall 2005, Fall 2007)
The course focuses on aspects of SPMs to provide fundamental/theoretical background in connection with practical operations. Topics include adhesive contact mechanics, short & long-range force interactions, principles of Scanning Tunneling Microscopy (STM), electron tunneling, tip & surface preparation, AC and DC Atomic Force Microscopy (AFM), detectors, control systems, basics of piezoelectric elements, issues and solutions in SPM instrumentation, force/scale calibration, modeling of oscillating cantilever, force interactions with surface, stability conditions, optimization of AC/DC experiments, high-resolution AFM, force spectroscopy, energy dissipation at the AFM tip, lateral contact stiffness, scanning thermal microscopy, electrostatic force and Kelvin probe microscopy, capacitance sensing, quantitative magnetic force studies, near-field optical imaging, molecular spectroscopy, macromolecular deposition/unfolding/binding, atomic friction, quantitative mechanics at the nanometer scale, application of SPMs in biological systems. The course includes four laboratory assignments where basic and advance principles in AFM are taught, the appication of theory in instrumented nanoindentation is studied, and the measurement of adhesive energies at the nanoscale using SPM probes is conducted.
AE 360: Structures and Controls Laboratory (Spring 2006, Spring 2008)
This course examines theory and application of experimental techniques in aerospace engineering with emphasis on structural mechanics, vibrations, dynamics, and control systems. The course includes 2-hour lectures and 9 labpratory assignments with regular pre-lab and post-lab reports and memos.
AE 321: Aerospace Structures I (Fall 2006)
This course examines fundamental concepts in the linear theory of elasticity, including stress, strain, equilibrium, compatibility, material constitution and properties. Introduction to failure mechanisms and criteria. Application to plane stress/strain problems, beams in extension and bending, and shafts in torsion.
AE 322: Aerospace Structures II (Spring 2007)
This course examines fundamental concepts in the analysis of beams and shafts of monocoque and semi-monocoque construction, energy methods, theory of elastic stability with applications to buckling of columns, introduction to finite element structural analysis - with application to trusses, frames, and plane stress/strain problems.
