Hi moderator,
Thanks for your quick reply.
Take T1 as an example.Except for the last cycle, all cycles are correct.We set the crack length of last cycle number to 7, which is actually 7.46. According to the spreadsheet calculation, penalty score is about 4.333.But according to the formula provided, T = 2+10*7.46 = 76.6, A= exp (2.3) +1 ≈ 9.974, M = 1.So the penalty score we calculated is S = T*A*M ≈764.
Thanks.
