how can apply a tightening torque

Submitted by djebbar on

I use the abaqus present , how can apply a tightening torque between an implant (screw) and the bone with abaqus......... thank you

 

 

Guys, your best bet is to use a kinematic constraint.  I had a similar problem, but in my case I wanted to apply a rotation to a surface of nodes that only had 3 degrees of freedom (displacements only).  This was effected by the inclusion of the following lines in my .inp file:

 ** Constraint: Constraint-1

*Coupling, constraint name=Constraint-1, ref node=_PickedSet14, surface=_PickedSurf13

*Kinematic

 You then can apply the concentrated torque to the reference node.  In my case, I applied a rotation to the reference node.  It is only fair to say that I had to get some support from ABAQUS/Simulia support and generated everything initially in ABAQUS CAE.
