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.

Experimental Characterization of Textile Composites for Validation of Virtual Weaving

Sponsor: US Air Force (USAF)

Start Date: 5/20/19

End Date: 8/02/21

Abstract

Textile composites offer the ability to provide enhanced damage and durability protection for composite materials. The damage is inherently linked to the unique weaving signature’s imperfections and capturing this in a virtual manner will enable woven composites to be explored using an ICME framework through virtual building and testing. This work will build off of the digital element approach implemented through VTMS and developed by the U.S. Air Force Research Laboratory (AFRL). This multi-institution effort will help to develop the capabilities of the VTMS software along with providing a verification and validation of some of the damage initiation and growth analysis for complex textile composites. The results of this effort will help mature some of the methodologies and develop faster, more user friendly capabilities for researchers.
