Hello EveryOne!
In recent days I was Working on an Abaqus Simulation of a Composite SandwichPanel that is under a three-point bending test. I define hashin damage criteria for composite and a cohesive interaction between parts.
And there are two types of simulation that I,ve done: solid structures and shell. But in both of them, I faced this error: "interaction coefficient must be between -1.0 and 1.0".
I searched everywhere but nothing helped.
Does any expert familiar with this error?
Mohammad Reza Sharafi,
I think you entered the wrong information somewhere in the definition of contact and cohesive behavior. Check them again and make sure you haven't entered the wrong coefficient. For example, the friction coefficient.
Good luck
The error message you encountered in your Abaqus simulation indicates that the interaction coefficient you have defined for the cohesive interaction between the parts of your composite sandwich panel is outside the valid range. The interaction coefficient should be between -1.0 and 1.0.
Here are a few possible reasons for this error and some suggestions to resolve it:
If none of the above suggestions resolve the issue, it may be necessary to provide more specific details about your simulation setup, including the relevant input file or code snippets, so that I can assist you further in diagnosing and resolving the error.
