    Hi,

     

    the best way is to use Pretension manager

    Pretension Manager - Altair University


     

    check the following examples and tutorials:

    Hi All,

     

    I am doing a Investigation on a bolted joint in Abaqus.

    I have applied bolt pretension in One Load step and applied some external load on the next step.

    The steps are continuous an I have requested the section forces as output.

    As a result, I have section force in bolt equal to the applied pretension Force in first Load step. This is Okay.

    But, even on the end of second Load step, the section force remains the same which is almost equal to the Pretension value.

    On the other hand, the stress in the bolt is increasing. Does anyone have any idea regarding this?

     

     

    Thanks.
