Hello,

I want to do buckling analysis of Paper box. Which Material law is useful for this purpose and what material properties needed?

    Hello,

    My question: Can you do 'buckling analysis' with simple beam analytically? Do you have some theorical knowledge about this suject before doing with numerical?

    not much....... but have some ideas to calculate. If u have some techniques and knowledge, I would like to learn.

    Hi,

    Is the material model a  cardboard package (corrugated material) which you have referred as 'paper box'?.

    If so, for the corrugated cardboard material, it maybe better to use elasto-plastic material. Another solution to better model the corrugated cardboard material is to use solid elements with honeycomb material (LAW28, 50 or 68).

    Hello @George P Johnson

    Thank you...

    Material model is cardboard paper only. but not corrugated. It is simply cardboard paper for packaging carton. And thickness is very small.

    Hi,

    In this case you can try with an elasto plastic material model.

    Sorry, I don't think you need an 'elasto plastic' material for ... paper!

    I think all you need is 'linear buckling' analysis. So look for elastic material. Due to structure of paper box, maybe you need composite model?

    Hiiii,

    There is material law LAW 58 which is for fiber like structure. As paper material is fiber structure and behavior is also an-isotropic can I use LAW 58 for paper?

    Hi,

    I'm not sure whether fabric material can be used for modelling paper. But do you have all the inputs for this material law?.

    If you have, then you can give a try.
