Fatigue may be characterized as a progressive failure phenomenon that occurs by the initiation and propagation of cracks to an unstable size. Read more at Fatigue Analysis.
Fatigue and Fitness for Service evaluations were performed on pressure swing adsorption (PSA) vessels that were in service at a waste facility. These evaluations had not been performed as required by the ASME Boiler & Pressure Vessel Code.

Relay Bar Call Tom O’Donnell, PE to Discuss Your Engineering Challenges We were asked to perform the structural integrity and fatigue life of an original and modified longwall mining relay bar. Longwall mining is used to more efficiently remove underground coal deposits in large rectangular blocks. After a “pass” of coal has been mined, the …
