Design and optimization of dissipative elastic metamaterials and their applications for broadband blast and shockwave mitigation
(University of Missouri--Columbia, 2016)
Elastic/Acoustic metamaterials comprise a new class of composite materials that possess unique effective material properties owing to their locally resonant substructures. Because of the inherent local resonance mechanism, ...
Simulation-based design of patient-specific femoral locking plate using topology optimization
(University of Missouri--Columbia, 2017)
Femoral locking plates are orthopedic implants used in closed reduction of the fractured femur. These orthopedic implants designed using conventional methods apply finite element analysis to evaluate their performance. ...
Compact oscillating heat pipe and development of fuzzy copper or wicking structures
(University of Missouri--Columbia, 2008)
A central processing units (CPU) calculation speed is limited by the heat it produces. As the number of transistors and the clock speed of CPUs increase they become more powerful, but they also generate more heat which ...
Advanced guidance algorithms for the Ares V cargo launch vehicle
(University of Missouri--Columbia, 2008)
Launch ascent guidance is an area that routinely involves applications of optimization tools and optimal control theory. The vacuum ascent trajectory problem has been formulated as a two-point boundary-value problem with ...
