K = (σ√(πa)) * Y

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

The failure occurred suddenly, without warning, and was attributed to a crack that had grown to a critical size. The pipeline was inspected regularly, but the crack was not detected until it was too late. K = (σ√(πa)) * Y The team also

The team recommended that the pipeline be replaced with a new one, fabricated using a improved welding process and inspected regularly using non-destructive evaluation techniques. principles of fracture mechanics rj sanford pdf pdf work

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