A high strength steel has yield = 100 ksi and fracture toughness KIC = 150 ksi√in. Based on a particular non-destructive inspection the smallest flaw size that can be detected is 0.3 in. Assume the most dangerous crack geometry in the structure is a single edge notch with K, = 1.12σγπα. The structure is subject to cyclic fatigue loading in which max = 45 ksi and σmin = 25 ksi. The fatigue crack growth in this steel can be described by the Paris equation with C = 0.66 × 10-8 and n = 2.25. Estimate the fatigue life for this structure.

A high strength steel has
100 ksi and fracture toughness KIC
Tyield
150 ksivin. Based on a
particular non-destructive inspection the smallest flaw size that can be detected is 0.3 in. Assume
the most dangerous crack geometry in the structure is a single edge notch with K₁ = 1.12√√а.
The structure is subject to cyclic fatigue loading in which max = 45 ksi and omin = 25 ksi.
The fatigue crack growth in this steel can be described by the Paris equation with C =
0.66 x 10-8 and n = 2.25. Estimate the fatigue life for this structure.
