Elastically-isotropic mechanical metamaterials : theory and experiments
(Massachusetts Institute of Technology, 2019)
Lightweight engineering requires the development of low-density materials featuring high mechanical properties with an emphasis on high-specific stiffness and strength. Besides improvement in the composition of bulk ...
Mixed-integer convex optimization for planning aggressive motions of legged robots over rough terrain
(Massachusetts Institute of Technology, 2016)
Planning dynamic motions for a legged robot entails addressing both the continuous question of how its joints should move and the combinatorial question of which hand or foot should touch which surface and in what order. ...
Ductile fracture at intermediate stress triaxialities : experimental investigations and micro-mechanical modeling
(Massachusetts Institute of Technology, 2013)
Accurate predictions of the onset of ductile fracture play an increasingly important role in the design of lightweight sheet metal structures. With the development of virtual prototyping practices, most transportation ...
Characterization and science of an aluminum fuel treatment process
(Massachusetts Institute of Technology, 2018)
Presented is an inexpensive and highly effective method of activating bulk aluminum allowing it to react with water producing hydrogen gas and steam. The extreme energy density of the aluminum-water reaction, twice that ...
Robust adaptive control in the presence of unmodeled dynamics
(Massachusetts Institute of Technology, 2017)
With the advent of each next generation technology, demands for a rapidly reconfigurable control system yielding invariant performance under increasingly unknown or widely varying operating conditions becomes crucial. ...
