Mean grain size estimation for copper-alloy samples based on attenuation coefficient estimates
(University of Missouri--Columbia, 2011)A polycrystalline metal's grain size affects its mechanical properties; therefore, the ability to effectively and easily monitor grain size during a manufacturing process is critical. Conventional destructive tests utilized ... -
Optimization of electromagnetic acoustic transducers for nondestructive evaluation of concrete structures
(University of Missouri--Columbia, 2008)There are more than 130,000 prestressed concrete bridges in the United States with about 37,000 bridges being more than 30 years old. Prestressing steel strands are an important construction element used in these bridges ... -
A single-sided access simultaneous solution of acoustic wave speed and sample thickness for isotropic materials of plate-type geometry
(University of Missouri--Columbia, 2006)In ultrasonic nondestructive evaluation, acoustic waves are used to inspect and characterize materials. Two commonly measured parameters are material thickness and acoustic wave speed in the material. These parameters are ... -
The spatial cross-correlation coefficient as an ultrasonic detection statistic
(University of Missouri--Columbia, 2007)In ultrasonics, image formation and detection are most commonly based on signal amplitude. Matched filtering is an amplitude independent approach, but requires accurate template estimation. In this work, we introduce the ...
