The objective of this project was to evaluate the mechanical response of tendons of varying properties under compressive and shear loading, then correlate structural characteristics to functional mechanical properties. This project provides insight into microscale mechanisms responsible for multiscale strain attenuation of tendons under non-tensile macroscale loading
Testing Device
A custom built device was used to apply compressive and shear loads to tendon samples.
Histology
Sample Selection
Proximal and distal samples were taken from flexor tendons. Samples were then split into histology pieces and mechanics pieces.
Mechanical Testing
After a small preload, samples were subjected to Compression or shear loading.
