Pull-out of cone from conical opening

[icefea]

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

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.

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.
