ABAQUS analysis with Mohr Coulomb Plasticity
ABAQUS analysis with Mohr Coulomb Plasticity
(OP)
Hi everybody!
I'm trying to analyse a RC shell plate with a Mohr Coulomb Plasticity model but ABAQUS returns me this error:
*PLASTIC REQUIRES THE USE OF *ELASTIC, *HYPERELASTIC OR *HYPERFOAM
Error in job JobStaticoPiastra4: THE MATERIAL OPTIONS *CAP PLASTICITY, *CAST IRON PLASTICITY, *CLAY PLASTICITY, *CONCRETE, *CONCRETE DAMAGED PLASTICITY, *DRUCKER PRAGER, *FOAM, *CRUSHABLE FOAM, *MOHR COULOMB, *JOINTED MATERIAL AND *PLASTIC ARE MUTUALLY EXCLUSIVE
Error in job JobStaticoPiastra4: 400 elements are missing elastic property reference. The elements have been identified in element set ErrElemMissingElasticPropRef.
Job JobStaticoPiastra4: Analysis Input File Processor aborted due to errors.
Error in job JobStaticoPiastra4: Analysis Input File Processor exited with an error.
Job JobStaticoPiastra4 aborted due to errors.
In the PROPERTIES I have defyned the material CONCRETE with only the MOHR COULOMB PLASTICITY model. I have also defined REBARS in the SECTION definition.
I can't understand what is missing. Can anyone help me?
Thank you

I defyned ELASTIC properties but the error message is:
Job Job-1: Analysis Input File Processor completed successfully.
Error in job Job-1: *MOHR COULOMB NOT ALLOWED IN PLANE STRESS
Job Job-1: Abaqus/Standard aborted due to errors.
Error in job Job-1: Abaqus/Standard Analysis exited with an error - Please see the message file for possible error messages if the file exists.
Job Job-1 aborted due to errors.
I'm using a SHELL PLATE element in a 3D SPACE of model to reproduce a CONCRETE SLAB. Why can't I use a Mohr Coulomb Plasticity model for a SHELL element?
Thank you

"The Mohr-Coulomb plasticity model can be used with any stress/displacement elements in Abaqus/Standard other than one-dimensional elements (beam and truss elements) or elements for which the assumed stress state is plane stress (plane stress, shell, and membrane elements)."
Also, I tried to change the Element type (to use a PLANE STRAIN element with a SHELL PROBLEM) but I can't do it because in the MESH module --> ELEMENT TYPE you can only change from LINEAR to QUADRATIC element.
So you can't use MOHR COULOMB PLASTICITY with SHELL ELEMENT I suppose...
Thanks
