Arbitrary Beam Cross Section (ABCS)

[gotm]

Please,

I found the ABCS method described for example in the MSC Nastran 2022.1

Linear Static Analysis User’s Guide Ch. 4 page 137 onw.

that is, after an arbitrary cross definition, the complete stress recovery

for the whole cross section, with torsion and shear effects included.

It seems that a FEM for each section is generated (GRID and CTRIA6),

Nastran run with .f06 and .op2 up to Von Mises section plots also.

Is there any link to Patran menu?

Anybody has an exercise step by step?

You might get a 'best-response' to this issue in the E-T NASTRAN forum...
