Rubber Covered Rolls — The Nonlinear Elastic Problem
نویسنده
چکیده
The problem of the indentation of a rubberlike layer bonded to a rigid cylinder and indented by another rigid cylinder is analyzed. The rubberlike layer is assumed to be made of a homogeneous Mooncy-Rivlin material. The materially and geometrically nonlinear problem is solved by using the finite-element code developed by the author. Results computed and presented graphically include the pressure profile at the contact surface, stress distribution at the bond surface and the deformed shape of the indented surface.

Cavitation in rubber: an elastic instability or a fracture phenomenon?
It is by now well established that loading conditions with suffi ciently large triaxialities can induce the suddenappearance of internal cavities within elastomeric (and other soft) solids. The occurrence of such a phenome-non, commonly referred to as cavitation, can be attributed to the growth of pre-existing defects into fi nite sizes.In the fi rst part of this discussion, I w...
