Biaxial testing is needed to evaluate the varying mechanical properties of fibrous soft tissue. A current gap in technology fails to effectively grip tissue so that each axis of load can behave independently of the other, while allowing an easy attachment method. The goal of this project was to develop a gripping and loading system that would allow force distribution, preserve the specimen, and have high usability. Using rapid prototyping, a gripping and loading mechanism was developed for a biaxial test device at WPI. Through the use of force distribution calculations and experimental testing, comparisons to current technology were made. From these results, the team can conclude that the objectives were met.
