WebCreep, known also as cold flow, is the permanent deformation that increases with time under constant load or stress. It results due to long time exposure to large external mechanical stress with in limit of yielding and is more severe in material that are subjected to heat for long time. WebThe interaction between creep and fatigue is particularly interesting for the rotating components subjected to sustained stress at high temperatures, such as the turbine section blades. This is a major limitation in much of the components’ designs …
