Abstract: | This paper communicates a novel and robust method for the mechanical testing of thin layers of soft biological tissues with
particular application to porcine skin. The key features include the use of a surgical dermatome and the highly defined deformation
kinematics achieved by pure shear testing. Thin specimens of accurate thickness were prepared using a dermatome and were subjected
to different quasi-static and dynamic loading protocols. Although simple in its experimental realisation, pure shear testing
provides a number of advantages over other classic uni- and biaxial testing procedures. The preparation of thin specimens
of porcine dermis, the mechanical tests as well as first representative results are described and discussed in detail. The
results indicate a pronounced anisotropy between the directions along and across the cleavage lines and a strain rate-dependent
response. |
