PPT-Creep Test A typical creep test consists of subjecting a specimen to a constant load or

m deformation or strain is measured and plotted as a function of elapsed time as illustrated in figure 2 For metallic materials most creep tests are conducted in uniaxial tension using a specimen having the same geometry as for tensile tests. Constant load creep tests were conducted on aluminum diecasting alloys B390 eutectic AlSi and a 17 SiAl alloys Rupture occurred in the primary creep regime with the eutectic alloy having the longest times to failure Primary creep was modeled by J 5 X.R.

Creep is a rate dependent material nonlinearity in which the material continues to deform under a constant load (ANSYS). Creep is highly time dependent and it displays its effects over a long time.

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. . 6.

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.
