ME 495/CIV ENV 495: Elastic Waves in Periodic Media

This course provides a basic understanding of approaches to exploit geometry and mechanical properties in periodic structures in order to realize novel system behavior. Some applications of these structures include, sound insulation in buildings,  earthquake protection, vibration cloaking of sensitive components, super-resolution imaging using elastic or acoustic waves, multifunctional sensors and actuators, and energy harvesting. In the course, we will explore analytical and numerical approaches to design and study the behavior of elastic waves in complex periodic structures. The course is intended for senior undergraduate students and first year graduate students. The course will provide the background needed to study elastic wave in complex structures and exploit them to produce un-usual dynamic behavior.

ME 495/CIV ENV 495: Nanomechanics and Nanomechanical Devices

There is a growing effort by scientist and engineers to envision, fabricate, and integrate nanoscale devices for applications in sensing, energy harvesting, and transport processes. This course will provide an introduction to basic concepts of nanomechanics, with particular emphasis devoted to the behavior of small objects subjected to time-varying forces. The course will cover a variety of topics including, theories of classical mechanical solids, quantum mechanics, thermal vibrations, and dissipation and noise in nanomechanical systems. Several novel applications of nanomechanical devices will be reviewed, and techniques for nanofabrication and characterization will be discussed.

ME 363: Mechanical Vibrations 

Complex machines often produce large oscillatory motion called mechanical vibrations as they operate. These vibrations can shorten the machine life, produce unpleasant noise, and hamper their functional performance and reliability. However, unwanted vibrations can be put to practical use, for example, by converting mechanical to electrical energy to power an electronic device, or using oscillatory structures as transducers to characterize the dynamic properties of complex structures. In this course, we will explore equivalent lumped parameter models and distributed systems to study the oscillatory motion of mechanical systems. We will use simple experimental tools like your mobile phones, accelerometers, and transducers, to record vibrations in complex real-world engineering structures, and also explore finite element modeling to simulate their dynamic response. The course is intended to provide junior and senior undergraduate students  with the background needed to understand and exploit oscillatory motion in engineering systems.

EA 206-2: Engineering Analysis: Statics and Dynamics

This course applies basic concepts from  the Newton’s laws of motion to study the equilibrium of engineering structures subjected to static mechanical loads. We will apply the matrix finite element method in Matlab to develop a truss solver and analyze the stress distribution in the truss elements. The course is intended for freshman undergraduate students in all engineering disciplines.
