Integrated strain actuation in aircraft with highly flexible composite wings
(Massachusetts Institute of Technology, 2003)
The purpose of this thesis is to provide a framework for the study of wing warping as a means of achieving multiple aeroelastic goals. Shape change is achieved by integrating anisotropic piezoelectric composites (APC) ...
Mechanics of abrasive wear of elastomeric materials
(Massachusetts Institute of Technology, 2003)
Elastomeric materials are widely used as tire and sealing materials due to their ability to undergo large deformations and conform to the mating surface. However, their applications often result in repeated contact with ...
Molecular mechanics of cartilage : quantification of GAG electrostatic interactions via high-resolution force spectroscopy
(Massachusetts Institute of Technology, 2003)
Intermolecular repulsion forces between negatively charged glycosaminoglycan (CS-GAG) macromolecules are a major determinant of cartilage biomechanical properties. It is thought that the electrostatic component of the total ...
Strain-tuning of periodic optical devices : tunable gratings and photonic crystals
(Massachusetts Institute of Technology, 2003)
The advancement of micro- and nano-scale optical devices has heralded micromirrors, semiconductor micro- and nano-lasers, and photonic crystals, among many. Broadly defined with the field of microphotonics and microelect ...
