In its current format, there have been cases of the FRI being misused in order to justify work patterns that clearly require further action to reduce fatigue-related risk. Number of cycles related to mean low cycle fatigue limit. Discuss with team/crew, decide on appropriate controls. 9 0 obj If the calulator is no longer available I wonder where this leaves this requirement. It recommends a more comprehensive approach to managing fatigue in a risk-based and systematic manner, and for fostering shared responsibility between an organisation and its employees. The Bolted Joint Analysis calculator allows for stress analysis of a bolted joint, accounting for preload, applied axial load, and applied shear load. <> Sleep disturbances can lead to a 'sleep debt' and fatigue.
