Note that 8 given by Equation ( 11 ) gives the displacement at the pipe centerline ( Figure 1a , point o ) rather than the Pure Stretch axis for perfect plasticity ( Figure 1a , point o ' ) , hence we obtain a conservative prediction ...

( applied stress exponent n ) of each isothermal line from equation ( 5 ) becomes -7.30 . Since the values of intercept of the log tr axis are the functions of temperature , the linear equation can be obtained as follows .
