MOMENTS OF INERTIA

MOMENTS OF INERTIA

(OP)
Hi,

I need to calculate the moments of inertia of the structure of a bus falling laterally. I know that in the .sta file ABAQUS writes the moments of inertia about center of mass and about the origin. Can ABAQUS calculate it about a point that I want it to calculate?

Thanks in advance,

Why not use the parallel axes theorem?

RE: MOMENTS OF INERTIA

If you have the MOI about the CG, it's not clear to me what else you need. You need to clarify your question.

RE: MOMENTS OF INERTIA

Do you mean moment of inertia (mk**2) or second moment of area?

RE: MOMENTS OF INERTIA

(OP)
Hi,

In fact I have to calculate both of them; with the Steiner theorem and the .sta fila I can calculate the moment of inertia in the point I want, but how can I calculate the other inertia, the area inertia, in ABAQUS?

Thanks in advance,

ferro1001
