Ultrasonics Research and Development Lab
Under the direction of Joseph Rose, Paul Morrow Professor of Engineering Science and Mechanics, the Ultrasonics Research and Development Lab in Penn State's Engineering Science and Mechanics department performs basic and fundamental research in ultrasonic guided wave and display technologies.
Research and experimentation is designed to quickly lend to technology transfer and product development in the areas of nondestructive evaluation and structural health monitoring. Said technology is applied to such problems as pipeline, rail, aircraft, power generation, civil structures, military ventures, and ice detection and deicing applications. Theoretical analysis and modeling, along with theoretically driven experimentation, is the foundation of all work efforts.
A fully equipped ultrasonic nondestructive evaluation facility is available, which includes an entire series of piezoelectric sensors and electromagnetic acoustic transducers that are available over a frequency range from 50 KHz to 25 MHz. Five shock and tone burst instrumentation systems are also available. The facility also includes an eight-channel phased array tone burst system to do focusing in pipe, a laser-based ultrasonic test system, and a set of air coupled sensors.
Computer modeling and computational software are also available to generate dispersion curves and wave structures for all sorts of geometries including plates, pipe, multiple layer structures, rail, rods, and other shapes. Programs for anisotropic and viscoelastic structures can also be integrated into the programs.
Elastodynamic wave propagation and scattering finite element and boundary element codes are also available for wave propagation and wave scattering from defects for a whole series of different wave guides.
