skin-passing is plane-strain or plane-stress?

[ab110]

Hi All,

I want to simulate a skin-passing process of a strip in 2D environment (the photo is attached). The dimensions of the strip are 1000, 2, and 70 mm in direction X, Y, and Z respectively. My question is for this 2D analysis should I consider plane-stress elements or plane-strain? I am in doubt whether this analysis is plane-stress or plane-strain, so I appreciate if someone please help me.

I want to simulate this process as implicit analysis.

If I've read your post correctly, the process sounds quite deep (into the page) which normally indicates plane-strain as there's really nowhere for material to deform into in the z direction (the conditions of the material are much the same wherever you are along the z axis so they'll push back the same amount). Plane stress condition is usually used in 2D simulations where the material is thin WRT the z axis.

https://en.wikipedia.org/wiki/Plane_strain#Plane_strain

has an alternate explanation.

The ABAQUS 6.10 example problems manual section 1.3.6 describes a rolling operation and also uses plane strain for the initial simulation.

Thanks Prntscrn for your reply.
