Formulation method in connections

[ISBind]

Greetings

Can any one tell in what cases which formulation method should be used for bonded connection and no separation (MPC or Pure penalty) ???

Also which formulation method to use for frictional, friction less and rough connection???

Thanks

Hi,

Mostly you can use pure penalty method for both bonded and no separation contact but especially if you use contact between face/edge or edge/edge mpc method is more useful and efficient. Augmented Lagrange method is default option in Ansys for non linear contact such as frictional, frictionless and rough contact.
