My MS/Ph.D. project is being conducted via collaboration between the Materials Science
and Engineering Dept. and the Mechanical and Aerospace Engineering Dept. The
project involves determining the effects of changes loading rate (i.e. strain rate) and
specimen geometry (e.g. length to diameter ratio) on the compression behavior of Zrbased
and Fe-based bulk metallic glasses (BMGs). The BMGs are being tested after
different annealing treatments designed to change the strength and fracture mechanisms
in order to determine the effects of such systematic changes in structure on the flow,
fracture, and energy absorbing behavior under dynamic test conditions. Tests are being
conducted primarily using Split Hopkinson Pressure Bar (SPHB) testing at room
temperature. Ultra-high speed video (e.g. 200,000 frames/sec) is being utilized to
determine the sequence of events that occur during deformation and fracture of these
materials when tested at strain rates in excess of 10,000/sec. These experiments are being conducted in collaboration with Prof. Vikas Prakash in the Department of Mechanical and Aerospace Engineering at CWRU.
