KIC = σ√(πac)

The team also discovered that the pipeline had been subjected to a series of pressure cycles, with pressures ranging from 500 to 900 psi. These cycles had caused fatigue cracks to form and grow in the weld region. principles of fracture mechanics rj sanford pdf pdf work

da/dN = 10^(-10) * (50 MPa√m)^2.5 = 2.5 * 10^(-5) inches/cycle KIC = σ√(πac) The team also discovered that

K = (900 psi * √(π * 2 inches)) * 1.5 = 85 MPa√m The team decided to apply the principles of

where Y is a geometric factor that depends on the crack configuration and the component geometry.

The team decided to apply the principles of fracture mechanics to analyze the failure. They used the stress intensity factor (K) to characterize the stress field around the crack tip.

The team integrated this equation over the number of pressure cycles to estimate the final crack length:
