State any assumptions made in order to arrive at your approximation.
The following creep data were taken on an aluminum alloy at 480 C (900 F) and a constant stress of 2.75 MPa (400 psi). Plot the data as strain versus time, a) then determine the steady-state or minimum creep rate. Note: The initial and instantaneous strain is not included. b) Identify at what time can a secondary creep region occur and at what time would it end to start the tertiary region in a creep curve: (see attachment).
