Unfortunately I can not share the file but for a cantilever plate (the real problem has a more complex shape) is it enough to analyze it with elements pshell with mid2 and mid3 blank? or do you advise some different set up?
Hi,
Can you please let me know what Altair product you are using so that I can direct your query to the proper forum?

Hi Giovannipario,
If you are defining PSHELL with MID2 and MID3 blank, then in Optistruct it will be considered as membrane element. Pure membrane in plane stress – no bending, coupling, or transverse shear stiffness. If this is your requirement you can go ahead else there is no need to have MID2 and MID3 as blank.
Thanks

Thanks for the answer, but my updated question is: Is it right to use PSHELL and MID3 blank to correctly analyze a thin plate bending problem (t/l < 1/20) or is it better use another type of element or set up of PSHELL?
Yes, for thin shell you can have MID3 as blank. with this no transverse shear deformation is not considered.
