Sol 101 with MATS & TABLES1 or sol 106?

[flyforever85]

Hi all,
I've been using Nastran on and off in the last year, my FE software is hypermesh. I have a problem where my component is deforming enough to go plastic but it should be any close to ultimate stress. I need to re-run the analysis with a elastic-plastic model to be confirm this. I read how to use MATS and TABLES1 cards, I'd like to know if I can use SOL101 when I use these cards or I should use SOL106 or SOL400.

Thank you

Did you mean using the MATS1 card? If so you will have to use a nonlinear solution sequence. This is listed in the QRG.

"Specifies stress-dependent material properties for use in applications involving nonlinear materials. This
entry is used if a MAT1 entry is specified with the same MID in a nonlinear solution sequence (SOLs 106,
129 and 400). For SOL 400 the MATEP option is the recommended approach for elastic-plastic
materials."

Thank you! Yes, I was wondering if SOL101 still considers MATS1 or I need to set up a SOL106. I've never done it before so I have to look into it.
