1.4.15 Mass and rotary inertia elements

Product: Abaqus/Standard  

Problem description

Model:

Isotropic mass 
100.0
Anisotropic mass 
100.0
200.0
300.0
Rotary inertia 
100.0
200.0
300.0
Centrifugal axis of rotation(0, 0, 1) through (0, 0, 0)
Gravity load vector(0, 1, 0)
Rotary acceleration axis(0, 0, 1) through (0, 0, 0)

The ROTARYI element and anisotropic MASS element are also tested with local coordinate systems and with finite rotation.

Results and discussion

The calculated reactions are in agreement with the applied loads.
