It depends on the loading conditions.
If it's being repeatedly loaded, you can do fatigue analysis and then plot S-N curves
Thank You Abhishek,
'material force' is a parameter used for characterizing durability. this is similar to that of 'J-Integral'. However, abaqus has option of plotting J-integral not the 'material force'. Many research papers suggest some post -processing steps after following those steps we can plot 'material force'. It ask for little bit of coding and I wanted help on that front.

If you know how to calculate the "Material force" ( I mean theoretical formulae), then you can write a Python script to access stress/strain/displacement fields from *.ODB files and calculate it.
Attached paper may probably help you. At the end of the paper some formulations are given.

Great Help Anshul. Could you please help on application side as I am more oriented towards application ( rather than theory ) . Often You PhD guys come for my rescue. If some application sort of text is available, please forward it.

HI Ujjwal,
I have never worked with "Material force". In the document which I sent earlier Sec. A.1.3 (at the end) suggest a way to numerical implementation. To implement that using PYTHON script you should know basics of FEM (like shape functions, stress and strain calculation).
You should also know bit of PYTHON language. For more information about PYTHON and ABAQUS interface to access information from ABAQUS ODB, please refer Sec. 34 from the given link.
I have also attached a paper which given detailed FE formulation for calculation of J integral, if it helps you in some way.
