What: This seminar will be delivered via Zoom as part of the Rocky Mountain Mechanics Seminar Series by Abigail Juhl, Materials Research Engineer in the Materials and Manufacturing Directorate at Air Force Research Laboratory.

Abstract: Control of mechanical wave propagation is key to Air Force applications in vibration damping, battlefield acoustics, non-destructive evaluation, ultrasonic imaging, impact resistance and aeroacoustics.  Many of the commercial solutions available in these application areas are parasitic in that they are added after structural performance optimization, they are not in a form factor that is desirable for the U.S. Air Force/Space Force, or they are too large and massive to be used on an aircraft. However, resonant metamaterials have emerged as a promising material set to overcome many of these problems. Emerging additive manufacturing technologies coupled with material innovations and a fundamental understanding of the dynamics of a structure have spurred the development of new metamaterial solutions for many Air Force problems. This talk will provide an overview of a few of the research projects on resonant metamaterials in the Materials and Manufacturing Directorate of AFRL including projects on low frequency sound mitigation, low frequency vibration control, ultrasonic imaging, and controlling instabilities in aerodynamic flow.
