Creep of the materials
Does creep exists for all materials at any stress at room temperature? I searched for this and could not find any answer other than creep isn't significant at low stresses and low temperatures. What I want to know is if the creep is present at low…

Ansys Norton creep power law constants?
I’m trying to learn creep analysis in Ansys, and am currently working on deriving creep constants, specifically C1, C2, and C3 for the Norton Power Law.
I understand that the equation is usually shown in 2 ways:
$$\dot\epsilon = A \sigma^n…

Would 6061 or 5052 Aluminum have lower rate of creep?
I am making a device which uses a bent thin sheet of aluminum as a spring which provides a constant force. It must be made of aluminum. Over time the material will relax and the force of the spring will decrease. I am wondering if there would be…

Calculating Creep
For a low-carbon steel part that will be put into a long lifetime use (10 years plus) what are recommended load cases to consider creep? The part I'm specifically working with will have a relatively low cycle count (20k load cycles over ten years)…
