How to extract the strain concentration tensor while using the Mori and Tanaka formulation built into Abaqus in the input file. Please advise me on how to extract this value from the output file.
Pandi Pitchai The Abaqus Python scripting interface is required to extract the average and global strain concentration tensor from an Abaqus output database (ODB) file. The following is a broad summary of the steps:
1. Open the ODB file via the odbAccess module's openOdb function.
2. Using the odbAccess module's relevant function, such as odb.steps['Step-1,'] extract the necessary field data.frames[-1].fieldOutputs['PE'], where "PE" is the field output name.
3. Using the Mori-Tanaka formulation, compute the strain concentration tensor by averaging the strain over the material volume, computing the strain tensor for each particle in the volume, and summing the contributions from each particle weighted by their volume percent.
4. Save the generated values to a file or use them for additional analysis as needed.
More thorough information and examples of how to utilize the Abaqus Python scripting interface to extract data from ODB files can be found in the SIMULIA website's Abaqus Scripting User Manual.
But there are some inbuilt option to recover the micro mechanics output (like Element field output "Micromechanics") while using MT formulation in the input file.
Let me know if you recovered solution at anytime using those inbuilt command line. Thanks
