WebFlow potential eccentricity, . The eccentricity is a small positive number that defines the rate at which the hyperbolic flow potential approaches its asymptote. If this field is left blank or a value of 0.0 is entered, the default of is used. WebApr 7, 2024 · But default values of flow potential eccentricity and viscosity parameter works fine because these two have negligible influence in the prediction accuracy. This default value of e indicates that the dilation angle in the p–q (hydrostatic pressure–deviatoric stress) plane converges to Y reasonably quickly with increasing hydrostatic ...
WebMar 13, 2024 · The default value of the flow potential eccentricity is 0.1. The flow potential is smooth and continuous, and it ensures that the flow has only one direction. In case the hydrostatic pressure axis and the high confining pressure intersect at 90°, the function form is approximated by the linear Drucker–Prager model. WebThe default for the eccentricity value of 0.1 is set for the flow potential so that almost the same dilation angle with constant curvature is used over the wide range of the confining hydrostatic pressures. In this chapter, the default value of 0.1 was used for the eccentricity to construct the flow potential function.
WebThis flow potential, which is continuous and smooth, ensures that the flow direction is always uniquely defined. The function approaches the linear Drucker-Prager flow potential asymptotically at high confining pressure … WebJun 26, 2024 · Friction stir welding with different pin-eccentric stir tools (the pin eccentricities were 0, 0.4, and 0.8 mm, respectively) was successfully utilized for joining dissimilar aluminum alloys AA5052 and AA6061, and the influences of pin eccentricity on the microstructural evolution and mechanical properties of joints were investigated.
