Corrugated flexible box(CFB) behavior

Altair Forum User

Hi,

I completed the vibration analysis with SPH elements(used for fluid).

Also got the expected behavior,but there is some weird behavior of CFB.

I didn't made CFB with multiple ply(only single ply) and material defined by MAT LAW 2.

Material for CFB used same as bottle(i.e HDPE).

Please check the shared video and suggest that reason behind the weird behavior of CFB.

Is the material parameters assigned for HDPE is right?. Seems like the issue is related to it.

Altair Forum User

Yes,material assigned for CFB is HDPE.

Will check material again and trying to get the properties for CFB.

Also Request you suggest the material law for CFB(If not MAT LAW is used for CFB/paper).
