Research Description

Dr. Pankow's long-term goal is to contribute to the advancement of our understanding of high impact bio-mechanics with an emphasis on the mechanical effects on the skull-brain system. Dr. Pankow is presently studying the underlying failure mechanisms in blast loading on composite materials. This study is being performed experimentally and is drawing its data largely from high-speed image capture of blast samples. The results can be applied to blast resistant structures (aircraft, buildings, etc). He is also currently studying blast structure-human interaction. This study examines the effects of shock-wave loading on skull-brain systems that vary in their mechanical properties. This research is aimed at applications that reduce the risks of traumatic brain injury.

Spectral Profile Multiplexing of FBG Sensors to Enable Low-Power Optical Sensor Networks

Sponsor: National Science Foundation (NSF)

Start Date: 9/01/15

End Date: 8/31/18

Abstract

We propose to derive and implement a novel multiplexing strategy for large FBG sensor networks that would enable the interrogation of these networks with low-power, low-bandwidth sources. The ultimate goal is to permit the integration of FBG sensor networks into wireless communication systems. The multiplexing strategy is based on identifying the unique spectral profile of each sensor through a rapid, cross-correlation algorithm. The cross-correlation algorithm will be supplemented with penalty functions based on prior information to reduce identification errors. The multiplexing strategy will be demonstrated on two applications: crash testing of automotive composites and lightening strike identification.

High Repetition-Rate Shape Sensing Using Fiber Bragg Gratings (HISS)

Sponsor: US Dept. of Defense (DOD)

Start Date: 9/09/15

End Date: 9/08/18

Abstract

The objective of the proposed effort is to develop a technology that will enable high repetition-rate shape sensing in a wide range of settings and can be integrated into the protective materials. The focus of this technology development is to improve the measurement of dynamic back face deformation (BFD) of body armor at a high repetition-rate. This will overcome two deficiencies in existing body armor testing and evaluation. First of all, the measurement system can be embedded into the material that simulates the body and does not require an exposed view of the backing material under test. Furthermore, it enables dynamic measurement of the BFD, not just post impact analysis of the deformed backing material. This allows researchers to perform a more realistic potential blunt force trauma analysis.

REU Site: Summer Internships in Composites for Extreme Performance

Sponsor: National Science Foundation (NSF)

Start Date: 2/01/15

End Date: 1/31/18

Abstract

Advanced composite materials are revolutionizing the fields of transportation (including the aerospace, naval, automotive, and rail industries), alternative energy generation and infrastructures. In this REU Site, the student interns will be paired with individual research mentors and will spend the majority of their experience working in the laboratory. In addition, the interns will attend weekly interactive research training seminars with their cohort and will participate in two site visits to advanced composite industries in North Carolina. As part of their research experience the interns will prepare and present a poster at the Undergraduate Research Symposium at NCSU. To incentivize the poster quality, the top three posters will be selected from the cohort and the winners will be funded by the REU site program to present their research at the SAMPE meeting in the following spring.
