Re: cyclic load ,isotropic hardening material,ansys

[Subject Prev][Subject Next][Thread Prev][Thread Next]
It is a more rational choice as isotropic hardening should be used only when there is an increase in both tension and compressive yields due to hardening.

I have built a kind of steel connection finit element model in ansys v.9.
In experimental model the yielding mode of this connection is shear
yielding.
Therefor,because of that behaviuor ,the material properties of the finit
element model
must be a steel material with an isotropic hardening(bileanier or
multilinear Isotropic Hardening)
and the load that applying to the model is the cyclic load(displacement
control) according to the SAC protocol.
ansys help has suggestioned that isotropic material can be used for
non-cyclic load histories.
Does any body know if I can use the kinematic hardening for this problem?
moment-rotation of connection with Isotropic Hardening is not rational.
