Experimental design for uniaxial tensile measurements at the microscale
Conference Dates
October 1-6, 2017
Abstract
Bone’s unique combination of mechanical properties like strength, stiffness, toughness and low weight are the result of its complex hierarchical structure spanning several length scales. Despite extensive research on bone, there is still a lack of understanding on how its micromechanical behavior relates to its macroscopic failure behavior. While recent research has mostly utilized microcompression and nanoindentation, pure tensile testing at the lamellar level has not yet been reported. Nevertheless, critical failure events in bone are often attributed to tensile stresses. In this study a tensile experiment is designed using an in-situ micromechanical testing platform (Alemnis AG, Switzerland). The setup consists of a translatable silicon gripper driven by a piezo motor and a movable sample stage mounted atop a load cell. The setup is compact and can be installed within an electron microscope for in-situ testing.
