Dynamic Shear Modulus in Torsion of Human Dentin and Enamel

Dental Materials Journal, 1989
The dynamic shear moduli of human dentin and enamel were measured using a torsion pendulum over a temperature range from 23 to 150 degrees C. For dentin, the shear modulus slightly increased for temperatures near 50 to 100 degrees C, which was caused by a loss of free water. The peak in the loss tangent was observed near 75 degrees C.

Acoustically-induced slip in sheared granular layers: application to dynamic earthquake triggering [PDF]

, 2015
A fundamental mystery in earthquake physics is ``how can an earthquake be triggered by distant seismic sources?'' Here, we use discrete element method simulations of a granular layer, during stick-slip, that is subject to transient vibrational excitation

Spring-damper equivalents of the fractional, poroelastic, and poroviscoelastic models for elastography

, 2017
In MR elastography it is common to use an elastic model for the tissue's response in order to properly interpret the results. More complex models such as viscoelastic, fractional viscoelastic, poroelastic, or poroviscoelastic ones are also used.
