I want to model an Ibarra-Krawinkler hysteretic material for an infill compressive strut with these parameters:
Fy_strut , delta_y_strut
Fc_strut , delta_c_strut
Fr_strut , delta_r_strut
k_f_strut , k_d_strut (Pinching parameters corresponding to stress and strain)
According to this picture: http://uupload.ir/files/jqr8_strut_matrial.jpg
When I used "Hysteretic" material, it didn't converge and the results of pushover analysis would be clearly wrong.
Now, what is the solution? Which material is suitable for this aim?
Suitable material for an infill compressive strut

Re: Suitable material for an infill compressive strut
You can use Concrete01. Please see the below paper that has good match with the test results using this material
