plasticity of orthotropic material in abaqus cae
dear all
do anyone know how to simulate the plasticity of orthotropic material in abaqus cae?
your help will be highly appreciated.

The 2nd Sandia Fracture Challenge is here!
update, 7/24/2014: The information packet ("SFC2-challenge-v5.ppt") is no longer attached to this post (iMechanica has a file size limit of 1 MB, so we can not attach the 6 MB file). IF YOU WOULD LIKE THE INFO PACKET, PLEASE E-MAIL ME, blboyce [at] sandia.gov and copy Dr. Sharlotte Kramer, slkrame [at] sandia.gov. If you have an older version of the information packet, please also e-mail for the newest (v5) info packet.
We intend to send the shear calibration data to all those whose e-mail address I have by August 1st (sorry for the delay!).

Combined hardening parameters
Hi everyone
I am trying to use Abaqus with combined hardening (kinematic + isotropic ) material. Structural milled steel strain-stress curve was obtained through tensile coupon test (ASTM E8).
Please let me know how I can extract material property (C , ɣ , Q and b ) for property input?
It is my first approach to martial plasticity so any detailed explanations or examples would be appreciated.

The abstract submission for the 24th International Workshop on
Computational Mechanics of Materials (IWCMM 24) in Madrid, Spain, on
October 1st-3rd, 2014 is now opened. The deadline for abstract
submission is June 15th, 2014.
The workshop is intended to cover all aspects of modeling and
simulations of the mechanical behavior at different length and time
scales. The materials of interest range from traditional materials such
as metals, alloys, polymers and composites to advanced and emerging

ductile behaviour
I have done flat plate tensile test experiment with plate having u notch at different angle to get mixed mode behaviour.The experiment shows the force variation F(30 DEG)>F(45 DEG)>F(0 DEG)>F(60 DEG) While fem elasto-plastic model made in abaqus shows F(0 DEG)>F(30 DEG)>F(45 DEG)>F(60 DEG).
Can anyone tell me why this contradiction is there between experiment and fem model.

Prager's Hardening Rule
Hi all
I am currently investigating Prager hardening room which is stated as the simplist linear kinematic hardening rule. I was wondering if anyone has worked with this model and if so if you have managed to identify how to determine the constant used for the back stress equation
dα =C * dεp ( this is epsilon dot p which is the equivalent plastic strain)
Please can you let me know how to determine the constant C from experimental results?
