The design line of a structural part subjected to fatigue loads represents a straight line starting from the highest value as 700MPa at 2000 cycles and fatigue limit as 200MPa at 2.10⁶ cycles. Structural part is subjected to following load cycles every day in the following manner:
1 = 8 at 600MPa,2 = 100 at 400MPa,³ = 1000 at 190MPa.
Answer the following:
Obtain an equation for the - curve for the fatigue behaviour of the part?
