Creep and Fatigue Behavior of Materials

About the Subject:

In materials science, creep (sometimes referred to as cold flow) is that the tendency of a solid material to maneuver slowly or deform for good beneath the influence of mechanical stresses. It will occur as results of long exposure to high levels of stress that area unit still below the yield strength of the fabric. Creep is a lot of severe in materials that area unit subjected to heat for long periods, and customarily will increase as they close to their temperature.

          The rate of deformation may be a perform of the fabric properties, exposure time, exposure temperature and therefore the applied structural load. Depending on the magnitude of the applied stress and its duration, the deformation may become so large that a component can no longer perform its function.
