Flow stress
WebOct 12, 2024 · Flow-Stress Curves and Equations. Values of flow stress can differ by 30-40%, especially in the first forming steps. Another required piece of information is the testing procedure for the flow curves. Is it compression, torsion or tensile testing? The fundamentally different state of stress is subtracted from the values of the flow curve, … WebOn the other hand, the effects of different non-Newtonian flow parameters, such as the couple stress fluid parameter, the magnetic parameter, the variable fluid viscosity, the variable thermal conductivity parameters, the Brinkman number, the nanofluid and buoyancy parameters, and the rate of chemical reaction parameter, are carefully studied.
