MECH_ENG 495/CIV_ENV 419: ELASTIC WAVES IN PERIODIC MEDIA

QUARTER OFFERED

Spring : TTh 3:30-4:50 PM

DESCRIPTION

This course is designed to provide a theoretical background on the propagation of elastic stress waves in solids, a review of experimental techniques for actuation and detection of elastic waves, and an overview of state-of-the art applications of wave propagation in linear and nonlinear media. Case studies on elastic wave propagation in elastic lattices and metamaterials will be discussed.

MECH_ENG 363: MECHANICAL VIBRATIONS

QUARTER OFFERED

Spring : MWF 9:00-9:50 AM

DESCRIPTION

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.

GEN_ENG 205-2: ENGINEERING ANALYSIS II

QUARTER OFFERED

Winter : MTWF 9:00-9:50 AM

DESCRIPTION

This course applies basic concepts from 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.

MECH_ENG 495: Selected Topics: Nanoscale Thermal Transport

QUARTER OFFERED

Spring:TTh 3.30-4.50 PM

DESCRIPTION

Thermal energy storage and transport at the nanoscale occurs through the interaction of electrons, phonons, and photons. The objective of this course to address five fundamental questions namely, (1) how is thermal energy distributed among electrons and phonons? (2) how fast do the carriers move through a material? (3) how much thermal energy do each carrier hold? (4) how do the carriers scatter as they move through a material?, and (5) how do the carriers interact with material boundaries and interfaces? The answers to these questions will provide a basis for understanding the conduction of thermal energy in solid-state nanomaterials, and the design and control of thermal processes in heat-transfer, thermoelectric, thermionic, thermophotovoltaic devices and solar cells.
