Effect of particle size ratio of rubber to sand on small strain dynamic characteristics of rubber-sand mixtures

open access: yesYantu gongcheng xuebao, 2020
By using the GDS-RCA resonant column system, the dynamic characteristics of rubber-sand mixtures (RSMs) under different rubber contents, particle size ratios and confining pressures are tested, and the coupling effect law and mechanism of three factors ...

Research on Comparison of the Maximum Dynamic Shear Modulus Test [PDF]

open access: yes, 2012
Dynamic 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.

Sublethal mechanical shear stress increases the elastic shear modulus of red blood cells but does not change capillary transit velocity

open access: yes, 2020
Blood exposure to supraphysiological shear stress within mechanical circulatory support is suspected of reducing red blood cell (RBC) deformability and being primal in the pathogenesis of several secondary complications.
