Dear Richard Ay,

Based on your feedback, I had checked load case L10 = L8+L9, L10= L8-L9 and L10 = L3-L4 both showing the same results. Kindly clarify the L10 = L8-L9 incorrect case
Since the stresses are failing in range case L10 = L8+L9 or L10 =L3-L4 only whether it is compulsory to consider Load case L10
Please advise the expansion stress range case (L10) is really needed.
