... ). These magnitudes are similar to those reported in previous diffusivity studies in meniscus [ 16 , 18 ]. It was observed that anisotropy was not affected by the magnitude of compressive strain, suggesting that compression does not alter the mechanisms (pathways) of diffusion in the tissue of an individual molecule...

We show the presence of multiple unique waves from each excitation which we combine to solve for parameters of an incompressible, transversely isotropic (ITI) material: shear modulus, μ , shear anisotropy, ϕ , and tensile...

... to be homogeneous and isotropic. The material anisotropy of the bone tissue likely only has a small influence on the overall anisotropy of trabecular bone at the apparent level since the apparent level anisotropy is primarily due to the trabecular structure [ 44–46 ] (i.e., structural anisotropy). Likewise...

A correction factor technique was introduced that can be used to calculate the stresses in the ROI from the measured experimental loads at the clamps. Application of a correction factor technique to experimental biaxial results may lead to more...

In the current study we extend the LFE technique to (1) estimate the (complex) viscoelastic shear modulus in lossy media; (2) eliminate...

Uniaxial tests performed on excised strips allowed to measure the anisotropy in the corneal stiffness and to compare the stiffness of the cornea with the one of the sclera. Viscous properties of the cornea have been...
