Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Poster Description
This paper describes the effects of a localized (point)-mass non-uniformity located arbitrarily on a longitudinally vibrating piezoelectric rod. The point-mass non-uniformity is accounted for using the receptance method. Expressions for the natural frequencies, modes, and the forced solution for the non-uniform rod and corresponding impedance are developed in closed form. The model is experimentally verified using impedance data from piezoelectric rods with attached concentrated masses. Methods for back-calculating the location of the point-mass using the experimental impedance trace are also described. The modeling approach detailed in this paper is potentially useful in the design of piezoelectric transformers and health monitoring of piezoelectric sensors and devices, as well as other piezoelectric devices.
