Postdoctoral position with focus in ultrasonics

A postdoctoral position isavailable in the research group led by Dr. Joseph A. Turner in the Departmentof Engineering Mechanics at the University of Nebraska–Lincoln (UNL).

Candidates should have a PhD in EngineeringMechanics, Mechanical Engineering, Civil Engineering, Materials Science,Applied Physics or a related field. A strong background in experimentalultrasonics (B-Scan, C-Scan, velocity measurements, crack detection, ultrasonicimage analysis, scattering, etc.) is preferred. Knowledge of elastic wavescattering theory is highly desirable. The candidate hired will be responsiblefor guiding undergraduate and graduate student research, for leading projectswith minimal guidance and for assisting with the development of new researchproposals. Teaching opportunities may also be available for qualifiedindividuals. The position is available immediately for a period of one yearwith possible extension based on performance. Interested candidates should sendtheir CV, a research statement and contact details for at least threereferences to

Research interests of this groupare focused primarily on characterization of materials and microstructures atmultiple scales using ultrasound, nanoindentation, and atomic force microscopy.The wave propagation research is primarily associated with heterogeneous mediafor which deterministic analysis techniques are either unsuitable or toodifficult. Statistical approaches are used for obtaining importantmicrostructural information about these complex materials which include polycrystallinemetals, composites, concrete, geophysical materials, and biological materials.This work has both theoretical/numerical and experimental aspects for materialscharacterization and nondestructive testing purposes. The group is also studyingthe mechanics of nanoscale materials characterization using the atomic forcemicroscope (AFM) and nanoindentation. Of particular interest are dynamictechniques that can be used to extract viscoelastic properties. The group hasstrong U.S. and international collaborations with universities, researchinstitutes, national labs and industry.

Hi, I'm so interested to elastic wave propagation in solid medias. I have a question about. I'll be so pleased if you could answer. is it important the propagation of high frequency elastic waves in dynamic design of structures in impact's loading? for example if we have a kind of loading like hammer impact or explosion, is it important the elastic waves with frequencies about KHz or MHz? thank you for your consideration.
