چكيده فارسي :
The stress rate and strain rate methods in creep
evolution analysis are compared. For this purpose a
thick-walled sphere made of functionally graded
material (FGM) subjected to an internal pressure is
studied. All of the material properties except the
Poisson’s ratio have been expressed as a power function
of the sphere radius. It has been concluded from the
present study that, the stress rate method has a good
adoption with the strain rate method for lower time
increments, however by increasing time intervals the
agreement between stress rate and strain rate methods
decreases. It has also been found that the stress rate
method is faster than strain rate method.
