Local and global (from sample diameter evolution) strain measurements can then me compared to better understand the dynamic behavior of the material.
Variations to the experiment described were performed. The first deviation aimed at creating a plane-strain loading condition on longer tube specimens.
This sequence shows the expansion of the longer tube.

The second variation of the experiment looked at using a flat coil to accelerate a flat plate.
This image shows the of the flat plate specimen being accelerated by the flat coil.

High-strain rate deformation research
This research was performed during my time as Graduate Research Assistant at The University of Texas at Austin, under Dr. Krishnaswamy Ravi-Chandar.
The goal of this research was to utilize electromagnetic loading to study the high-strain rate behavior of aluminum samples.
The expanding tube experiment was used to study the effects of polymer coatings on cylindrical specimens. Modifications to this experiment were carried out to allow for testing of tubes under plane-strain conditions and unrestrained flat plates under rapid acceleration.
