Hi,
I am trying to simulate the Preloaded flange bolted connection similar to the one in wind turbine towers. I am using the cohesive behavior to model the surface to surface contact where I need to provide knn, kss and ktt for the cohesive behavior.
I have tried reading the abaqus manual for this but I am still not sure what to put for these values. Is there any formulas through which these values can be found?
Should I model a single bolt apply a preload and find the force/displacement graph and then fins the slope which i will use in place of these values?
Can anybody explain what is the actual meaning of these values and how to estimate them?
