Abstract Fatigue crack growth is represented using the Unified Approach in terms of two crack-tip driving forces, Δ K and K max . In this approach, crack growth is related solely to fracture mechanics parameters. Using this approach, crack-growth trajectory path can be defined in terms of Δ K ∗ – K max ∗ , which are two limiting values (they are the same as the thresholds when d a /d N =0), for a given crack-growth rate. Pure fatigue is represented by a line Δ K ∗ =K max ∗ (a 45° line in the… CONTINUE READING
