loiwng paper. We are presently working on an extension of the work using better hardening models. However, I couldn't find any published literature on the anisotropic effects on the strain-life curves for sheet metals. I will be glad to be notified if anyone come across such papers?

Not sure about sheet metals...but a number of works available on aluminum, other forging steels...they should give you some insights.
BTW, how are you conducting the fatigue tests on thin sheets (i suppose you are talking about strain controlled fatigue tests)...using anti-buckling fixture?
thank you Dr.Sivaprasad, i shall try some search on Al.
yes, its difficult to perform experiments in sheet metals without an antibuckling fixture.
