rotation of deformable shell ( rolling process)

rotation of deformable shell ( rolling process)

(OP)
hi

i decide to rotate a deformable circular shell part about it's central axis but my problem is after applying rotation , shell begin to deform axially! what should i do to constrain the this and make it rotate without any deformation?!

i'm going to use this for simulating rolling process.

kind regrad

RE: rotation of deformable shell ( rolling process)

For rolling the method is generally to model the roll as a rigid body and use solid elements (2D or 3D) for the material being deformed.

i knew that i could do it with rigid body, but i have another question on the table. in some rolling process, radius of Roller changes during the process and i want to simulate the new Radius that occurs after deformation of roller.
.
indeed i cant rotate a 2D deformable shell or 3D deformable body without expansion in the radial direction!

RE: rotation of deformable shell ( rolling process)

The image you included shows a flat disc. To create a uniform roll then you'd just extrude that disc along the axis. To create a non uniform roll then sketch the outline and sweep it around the axis for 360 degrees or whatever.
