Seminar
Dr. Brian Wisner
Department of Mechanical Engineering, Ohio University
Will present a talk titled:
Using Sound to Advance
Manufacturing, Energy Storage, and Damage Detection
Abstract: We use sound on a regular basis to communicate, trade information, or to relax. Given that sound is simply a vibration travelling through a medium, it can be used to affect materials in a variety of ways. This talk we will demonstrate a range of advances that can be accomplished by leveraging vibrational concepts in different ways. Focus will be on traditional and novel uses of sound waves in the form of Ultrasonic Testing and Acoustic emission Testing. Both methods are classified as sound based Nondestructive Testing and Evaluation (NDT&E) methods that have been used commonly for detecting damage in materials. We will discuss the common Acoustic emission Methodology and how it can detect damage across length scales and how modifications have made it possible to detect sound with optical methods. Additionally, we will visit how this same methodology can be leveraged in energy storage applications. Lastly, we will look at how sound can be used to alter the microstructure of a material during the additive manufacturing process.

Bio: Brian completed his Bachelor’s Degrees in Mechanical Engineering and Physics from Widener University in Chester, PA in 2011. He completed his Master’s under Dr. Surya Kalidindi at Drexel University in 2013 before moving to industry designing aircraft components. In 2014 he returned to Drexel under Antonios Kontsos to complete his PhD focusing on microscale sensitive nondestructive evaluation.
While completing his Degrees he worked for periods of time at the Army Research Labs in Aberdeen Maryland and Sandia National Labs in Albuquerque New Mexico. After completing his PhD, he completed a postdoc at Drexel focusing on structural health monitoring and larger scale components.
In 2019 he joined the faculty at Ohio University in the Mechanical Engineering Department. His work focuses on the use of Nondestructive Methods to monitor materials response to loads. He has had projects ranging from fatigue damage detection using non-contact Acoustic Sensors to altering grain structure with ultrasound. Recently he has expanded to using ultrasound methods for detection of defects in energy storage systems and in detecting defects in gene therapy samples.
