Products: ABAQUS/Standard ABAQUS/Explicit
This section provides basic verification tests for the *BEAM FLUID INERTIA option that can be used with all Timoshenko beams.
There are two sets of problems presented in this section. The first set includes the input files b21_circ_bfi.inp and b21_circ_bai.inp and verifies the use of the *BEAM FLUID INERTIA option in a *FREQUENCY analysis. The second set consists of the remaining input files and tests the use of the *BEAM FLUID INERTIA option in transient dynamic analysis with the *BEAM SECTION or *BEAM GENERAL SECTION option. The transient dynamic analyses are also performed using ABAQUS/Explicit to verify the *BEAM FLUID INERTIA option in ABAQUS/Explicit.
The results obtained from b21_circ_bfi.inp using *BEAM FLUID INERTIA agree well with the results from b21_circ_bai.inp, which uses *BEAM ADDED INERTIA to add equivalent masses.
The ABAQUS/Explicit transient analysis results closely match the transient analysis results obtained using ABAQUS/Standard.
