WebFlow Stress Behavior. The flow stress behavior of the material under consideration is dependent on strain, strain rate, and temperature, and hence the material is … WebMoreover, in the low strain rate regime, the measured flow stress and r-values are mildly strain rate sensitive at room temperature (81), while as the temperature increases, strong strain rate sensitivity is observed. Figure 7 shows the strain rate sensitivity of AZ31B at 200 °C for the low strain rate range 0.001–1.0 s −1.
WebThe shear stress corresponds to the dragging force generated by the friction of a moving fluid onto a surface. Thus, cells exposed to a fluid flow endure this shear stress, known to affect their phenotype, morphology and their maturation. You can use our Shear Stress Calculator to determine your experimental parameters.
