Dynamic Methods to Evaluate the Shear Modulus of Wood

open access: yesBioResources, 2015
There are different dynamic or static test methodologies for evaluating the shear and torsional moduli of wood. A preferred method is nondestructive, accurate, and standard. However, dynamic methods using conventional devices previously suggested for determining the orthotropic shear moduli of wood are neither accurate nor standard.

Research on Comparison of the Maximum Dynamic Shear Modulus Test

open access: yesProcedia Engineering, 2012
AbstractDynamic soil modulus and damping ratio are the two basic parameters to describe dynamic deformation characteristics of the soil. There are three ways to obtain soil dynamics parameters i.e. field test, laboratory test, and calculating empirical. Silt loam samples were collected from Dongying area in this study.

Structural relaxation time and dynamic shear modulus of glassy graphene [PDF]

open access: yesJournal of Non-Crystalline Solids, 2020
We theoretically investigate glass transition behaviors of the glassy graphene in a wide range of temperature, where this amorphous graphene is described as a hard-sphere fluid. The dynamic arrest of a particle is assumingly caused by interactions with its nearest neighbors and surrounding fluid particles.

Dynamic Shear Modulus in Torsion of Human Dentin

open access: yesDental Materials Journal, 1988
The dynamic shear modulus of human dentin was measured using a torsion pendulum between 23°C and 150°C. Dentin had a relatively stable modulus in spite of increasing temperature. The shear moduli at 37°C for 20 specimens were in the range of 5.77×1010 dyne/cm2-1.06×1011 dyne/cm2.
