SOLIDWORKS Simulation– Bonded & No-penetration
  • SOLIDWORKS Simulation– Bonded & No-penetration

    In setting up your simulation especially for your assemblies, things that we want to pay attention is the interaction between each component, whether they are bonded, can penetrate or no-penetration. In this blogs we will show you a bit about Bonded vs No-Penetration contact.

    SOLIDWORKS SIMULATION 1

    Case: we want to see the behavior of stresses and displacement of the handle when under 225 N for each handle. We are not interested with the sheet (object 4) so we can suppress the object 4 and apply an appropriate fixture to the model.

    Bonded Contact will make the component that touches each other be fully bonded / can be treated as 1 solid body.

    No Penetration Contact will make sure that the component still separate body even it touches each other and cannot penetrate into each other.

    Global Contact : Bonded Contact

    The result using bonded contact stress is shown below.

    SOLIDWORKS SIMULATION 3

    Global Contact : No-Penetration Contact

    The result of using the no-penetration contact shown below.

    SOLIDWORKS SIMULATION 4

    SOLIDWORKS SIMULATION 5

    From the result of both study, we can see that if using bonded contact the assemblies will behave like 1 solid body only, and it can not capture the stress distribution behavior. The Displacement result also differ from the no penetration study.

    Hopefully this brief comparison could be the starting point for you to start your simulation. Cheers !!
