A team of engineers was called in to investigate the failure. They began by collecting data on the pipeline's material properties, operating conditions, and inspection history. They also conducted a thorough visual examination of the failed component.
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. principles of fracture mechanics rj sanford pdf pdf work
This calculation indicated that the crack was not critical at the time of inspection. However, the team realized that the crack had grown over time due to fatigue. A team of engineers was called in to investigate the failure
K = 85 MPa√m < KIC = 100 MPa√m
