If the Poisson's ratio of the material if positive, then tensile/compressive strains in the x-direction produce compressive/tensile strains in the y- and z-directions, as shown below. Negative Poisson ...

The MgO tunnel barrier is subjected to compressive strain because of restraint from the underlying layers. We demonstrated that the dielectric constant of the MgO tunnel barrier and voltage ...

Methods: A strain gauged bone staple was mounted percutaneously along the axial direction in the mid diaphysis of the medial tibia in three subjects, and in vivo tibial strains were measured during ...
