Center
for Metabolic Bone Disease (CMBD) Experimental Biomechanics Core
Director: Alan W. Eberhardt, PhD
Department/Center Association: CMBD,
BioMatrix Engineering and Regenerative Medicine Center, Department of
Biomedical Engineering, Department of Physics, and Division of Orthopedic
Surgery
Established: 2006
Mission
The mission of the
Experimental Biomechanics Core is to provide collaborating investigators with
state-of-the-art equipment and trained personnel to facilitate mechanical
testing and measurement of mechanical properties of biological and man-made
materials, structures, and constructs.
Facility
Description
The Core is currently
housed in the Musculoskeletal Mechanics Laboratory (Hoehn
270-271, located at 1075 13th
Street South).
This laboratory contains 1,800 square feet of research space with
designated areas for specimen preparation and storage, and mechanical and
impact testing. Its available equipment
includes two MTS 858 Mini-Bionix Mechanical Testing
Systems, a VIA Systems Pneumatic Impactor, an Instron
Dynatup Drop Tower, an AMTI OrthoPOD
Friction and Wear Tester, high and low speed infrared cameras, strain gauge
equipment, accelerometers, an extensometer, inclinometers, LVDTs,
and displacement/rotation measurement equipment. A new Bose Low Force Testbench system, located in the Shelby
Interdisciplinary Biomedical Research
Building, and an MTS G200 Nanoindenter, located in the Lyons Harrison
Building, are now
available for use.

Core services include the
following: 1) mechanical testing at high (up to 25 kN)
and low (
Newton
and gram force) levels, 2) impact testing (linear horizontal and drop tower),
3) friction and wear testing, and 4) nanoindentation.
