ABAQUS Explicit - define rotary inertia for a rigid body reference node
ABAQUS Explicit - define rotary inertia for a rigid body reference node
(OP)
Hi everyone,
I have got the following problem I require some assistance with: suppose you got a rigid body (for instance,a rigid plate), which is globally restrained using boundary conditions on the reference node - every displacement and rotation is restrained, except for the vertical displacement of said rigid plate.
Now, I want to release one of the rotations, which requires the definition of a rotary inertia. My idea is that I need to define a ROTARYI element, which contains my rigid plate reference node.
*RIGID BODY, REF NODE=SupportPlate.40, ELSET=SupportPlate.SupportPlateElements
*ROTARY INERTIA, ELSET=??
I11, I22, I33, I12, I13, I23
My question is, how do I define the ELSET, which includes the REF NODE, as defined in the *RIGID BODY line?
Thanks in advance for any input on this.

RE: ABAQUS Explicit - define rotary inertia for a rigid body reference node
I have defined a rotary inertia element set (1 ROTARYI element, 1 node) with *ROTARY INERTIA. Now I want to associate this element with a rigid plate reference node, which is a well defined node set in my model. Does anyone know how to do this? It is worth mentioning I am writing an input file..

You need to define your inertia element at reference node of rigid body.
