Answer:
The strength coefficient and strain-hardening exponent in the flow curve equation are 92038 and 0.3608.
Step-by-step explanation:
Given that,
True stress = 37000
True strain = 0.08
Later,
True stress = 55000
True strain = 0.24
Using formula of true stress

We need to make a two equation of true stress
Using formula of true stress
....(I)
....(I)
Dividing equation (II) and (I)



Taking ln in both side



We need to calculate the value of strength coefficient
Put the value of n in equation (I)



Hence, The strength coefficient and strain-hardening exponent in the flow curve equation are 92038 and 0.3608.
