A novel shear-test device for soft biological tissue, capable of applying
simple shear deformations simultaneously in two orthogonal directions
while measuring the resulting forces generated in three axes, is
described. We validated the device using a synthetic gel, the properties
of which were ascertained from independent tensile and rotational
shear tests. Material parameters for the gel were fitted using neo-Hookean
analytical solutions to the independent test data, and these matched
the results from the device. Preliminary results obtained with rat
septal myocardium are also presented to demonstrate the feasibility
of the apparatus in determining the shear characteristics of living
tissue.
