Professor Murray’s research has focused on the development of novel techniques for the characterization of materials, structures, and biological tissues in a non-invasive manner. He has developed laser-based ultrasonic approaches for the measurement of elastic and thermal properties of nanoscale materials and for the detection of subsurface defects in, for example, microelectronic components. His research also involves multimode imaging approaches utilizing both ultrasound and light to detect abnormalities, such as early stage tumors, buried deep within biological tissue. Additional research interests include elastic wave propagation, nanoparticle based sensors, and the development of laser-based techniques to interface with nanoscale mechanical devices.

Fall 2018 / Fall 2020 / Fall 2021 / Fall 2023 / Fall 2024
Examines the fundamental concepts regarding the failure of engineering materials. Case studies are used to integrate a basic understanding of material failure mechanisms with analysis techniques and tools. Topics include the elastic properties (isotropic and anisotropic materials) and the origin of elastic behavior, viscoelasticity, plasticity (dislocation mechanisms, yielding criteria, strengthening mechanisms), creep, fracture and fatigue. Same as MCEN 5174.
