Need to input the steel plastic properties

... I'm working on a very basic Riks analysis step for a Castellated
Beam, but having a hard time in the results for the plastic
behaviour, I'm using metric units, but I'm not sure about, what info
should I feed the input file in order to get the correct behaviour in
the plastic area of the graphic "Stress-Strain" the information Im
using is as follows:


*****
*Material, name=ACERO
*Density
 7.7e-05,
*Elastic
199948., 0.3
*Plastic, hardening=COMBINED, datatype=STABILIZED
 165.47,       0.,     0.08
 455.05, 0.008333,     0.08
 510.21, 0.018333,     0.08
  517.1, 0.028333,     0.08
   524., 0.038333,     0.08
 537.79, 0.048333,     0.08
 544.68, 0.068333,     0.08
 551.58, 0.078333,     0.08
**

any advise?... thanks in advance

>Hi fernando
I think it is better that u  don't use combined option.
if ur material is steel u use plastic option alone then u must enter
the plasticity property. and it must have plastic strain equal to 0
(zero) at start point. i didn't underestand the datatype option , i
think it is good that u dont use this option too.
thank alot
