PPT-Creep is the tendency of a solid material to slowly deform permanently under the influence

The rate of this deformation is a function of the material properties exposure time exposure temperature and 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 for example creep of a turbine blade will cause the blade to contact the casing resulting in the failure of the blade .

Creep is highly time dependent and it displays its effects over a long time. Creep has 3 stages:. VIRGINIA CONCRETE CONFERENCE. March 3-4, 2011 . Presented by:. Teddy Theryo, P.E..

Rheology is the study of flow of matter. In dentistry, study of rheology is necessary because many dental materials are liquids at some stage of their use, e.g. molten alloy and freshly mixed impression materials and cements.
