Pull-out of cone from conical opening

Pull-out of cone from conical opening

Pull-out of cone from conical opening

(OP)
Hi Everyone,

I have been using contact manager to help me run a basic model to simulate force variation during pull-out of a geometrically restrained object. To start off with, I am looking at the pull-out of a cone from a conical orifice.

The orifice material is rigid so I do not mesh it, and the cone is based on a linear elastic material model. I have applied a displacement loading constraint, howver, when I animate the deformation response, the boundry of the cone passes through the boundary of the orifice - i.e. the two surfaces are not contacting properly. I am not using the advanced options in contact manager, and ignoring friction.

Does anyone know what if going wrong with my model?

Thanks,

icefea

RE: Pull-out of cone from conical opening

You may have checked, but couple of simple things to check again: 1) Contact Normals 2) Try with Symmetric Conatct 3)Use contact option such that initial gap or penetration is zero.
Hope this may help you.

RE: Pull-out of cone from conical opening

Also, be sure you have defined a "rigid-flexible" contact, i.e. you have chosen "rigid target", otherwise contact will be driven by the properties of the underlying elements (that aren't present in your target...), leading to a void contact.
