The formula to calculate Flow Stress (FS) is:
\[ FS = T^{SHC} \cdot SC \]
Flow Stress is a function of plastic strain. True strain is the instantaneous elongation per unit length. Strain Hardening Coefficient (also called strain hardening index), noted as n, is a material's constant used in calculations for stress–strain behavior. Strength Coefficient is a measure of strain capacity.
Let's assume the following values:
Using the formula:
\[ FS = 0.01^{2.2} \cdot 5 \approx 0.000199053585276748 \]
The Flow Stress is approximately 0.000199053585276748.
