@SalahM07 u know in a lot of papers they used "tie constrains" & "DOF coupling method" instead to model the self drilling screws, i'll compare the results in my next model to see the difference between modeling direct fastener like what u did & the other techniques. if u have an idea beteeen the difference between them i'd be gratefull.
@@Infinite-life-seeker Good idea! It will be more intersting to compare the FEA results with tests, to see which method gives the more accurate results in your specific case Good luck!
