Rigid element - young's Modulus - density
Rigid element - young's Modulus - density
(OP)
Hello,
I'm a new member of Abaqus and I want to model a solid rigid body part (revolution) (steel: E-modulus = 210*10^9MPa and v=0.2) and deformable part (revolution) (sand). (See attachment bucket with surrounding soil).
http://files.engineering.com/getfile.aspx?folder=3...
However, I is not possible to give a rigid part section assignments? I already tried to give the rigid part a nonstructural mass - total mass but then I get the error:
"MASS PROPORTIONAL DISTRIBUTION OF NONSTRUCTURAL MASS IS NOT ALLOWED WITH ELSET ASSEMBLY_BUCKET-1_SET-2 AS NONE OF THE ELEMENTS HAVE A STRUCTURAL MASS. PLEASE DEFINE A DENSITY TO GENERATE STRUCTURAL MASS OR, IN ABAQUS/Explicit ONLY, USE VOLUME PROPORTIONAL DISTRIBUTION."
How can you define a density to the rigid part if it's not possible to use section assigments?
many thanks in advance
Matthias

If you want a rigid body on Abaqus CAE you have to select that option when creating the geometry for the part.
The mass is taken care of when you assign the parts inertial properties.

I dont think its possible to do what you are asking. If you want a rigid body then you have to construct the geometry as rigid to start with.
If the part is rigid then assigning something like Young's modulus has no meaning as the stress state of the part is not calculated for rigid bodies.
Does that make sense?

If so this could solve a nagging problem I've been thinking about.
