Analytic Plane
Problem Description
Fig. 43 Analytic Surfaces problem set-up.
The purpose of the following numerical example is to display how to setup a problem using analytic surfaces. Consider a cylinder hovering above an analytic surface and to the right of an angled analytic surface.
Loading and Boundary Conditions
A prescribed displacement is applied to the angled analytic surface in the upper left, and a fixed displacement is applied to the analytic surface below the cylinder. To see how the analytic surfaces are created, how the boundary conditions are applied, and how contact is setup, see the input deck and mesh.
Feature Tested
Analytic surfaces with DASH contact.
Results and Discussion
The angled analytic surface is the first to contact the cylinder (Fig. 44). As the cylinder displaces, the cylinder contactsthe lower analytic plane and ricochets to the right (Fig. 45).
