Dear iMechanicians,
I want to share our recent work published in IJSS on the mechanics of spontaneously formed 2D crystal bubbles.
Two-dimensional crystals on adhesive substrates subjected to uniform transverse pressure

Hello everybody.
I am trying to use abaqus software to model the sliding of a metallic pile inside a metallic sleeve. I have tried doing this with the translator connector, but I always get the message that 2 regions in the model are not connected. Can anybody help me with some hints as to how to use the connector, or if there are any other ways to model the sliding?
I want to model a fiber rod pull out process in Abaqus. The fiber is a composite rod which is to be debonded first from the surrounding laminate and need to be sliding along the interface of the rod/laminate.
Modelling:
i created an axisymmetric model of the rod being surrounded by the laminate. i got the residual stress due to curing process. This residual stress is compressive at the interface which is responsible for resisting the pull out force applied at first.
loading:
Axial pull is applied at one end of the rod. and the other end being fixed.
Graduate assistantship positions are available in the Computational olid Mechanics Laboratory (http://lsms.epfl.ch/) at the Ecole olytechnique Fédérale de Lausanne (http://www.epfl.ch/).
We are interested in highly motivated Ph.D. candidates with an academic background (B.S. and M.S.) in either Mechanical Engineering, Civil ngineering or Computational Materials Science.
