I am trying to simulate a mixed mode bending test in Abaqus using cohesive elements. To get the load-displacement curve, I am trying to implement the Riks method, but getting the following warning: EXCESSIVE DISTORTION AT A TOTAL OF 20168 INTEGRATION POINTS IN SOLID (CONTINUUM) ELEMENTS, CONVERGENCE IS JUDGED UNLIKELY and subsequently Abaqus is aborting the simulation. I am attaching the input file I am using with the message. I am not sure why this is happening, any help is appreciated.
Good question.. Please share me the best answer might you trust...

Gourab Ghosh I have faced these errors. Since the problem you which to solve is little ambiguous, I'll like to give a suggestion based on my experience.
Check if your material properties are correct. Sometimes, material don't posses enough strength to handle the stresses resulting to these errors.
Thanks for the suggestion. I have checked the material parameters, they are correct.
