  Hi all. Colleagues, share your experience. How often do you use plastic (plastic properties of steel) when calculating metal frames using the beams and shells method? How necessary is this? I think we can get by with isotropic properties.

  Hi Javat,
  It depends on the loading conditions. If the material remains below the yield stress, then its elastic properties are sufficient. However, if the loading exceeds the yield stress in the material, then it is better to use elastic-plastic material properties for the analysis.
  For further information, you can check out this AIS course.

    Thanks for the answer. I saw this course. I was interested in people's experiences and their words. Thank you, it's clear now.
