Biaxial Tensile Testing

The question of meningeal tissues anisotropy is complex and should not be limited to the comparison of uni-axial tests in various directions. Bi-axial mechanical testing enables quasi-static characterization in conditions closer to physiological context while requiring development of specific testing system as well as specific post-processing analysis. Combined to microscopy to provide an identification of the meningeal micro-structure, this study aims at identifying mechanical characteristics under bi-axial loading conditions of extracted swine pia mater (PM) and dura and arachnoid complex (DAC).
