Is there any material model, that takes into account the change in material stiffness with increased number of loading cycles. I have found the Kinematic Hardening Model on ANSYS. just wondering what other material models are out there
I wonder what class of material models you are looking for. Damage would be a typical class for which the stiffness decreases with load cycles. Kinematic hardening is not meant to model this effect.
If you are really looking for damage mechanics, here are 2 classical books:
Jean Lemaitre: A Course on Damage Mechanics. Springer (1996)
Jean Lemaitre: Engineering Damage Mechanics. Springer (2005)
Hello Mr Manfred
, well it is mainly a soil structure interaction problem. The stifffness of sand is changing with number of cycles. There is currently no commercial material model that I can find. So I was thinking of "Borrowing" other material models from other applications
Hello, Saleh Jalbi.
I adhere to Manfred Staat to confirm that the dynamic hardening model is not to deal with a problem stiffness variation . On the other hand, I advise you to see a model originally proposed for composite materials by "Mao and Mahadevan" and later developed by myself and validated on Polyethylene. This model is based on the theory of Lemaitre for the continuous damage mechanic that you can find on the two books indicated by Mr. Manfred Staat.
So see,
Mao,H. and Mahadevan,S., Fatigue damage modeling of composite materials. Composite Structure, 2002, 58(4): 405-410
