In nonlinear contact analysis, the initial geometric relationship between two surfaces can strongly influence both convergence and the physical meaning of the solution. Before external loading begins, Ansys evaluates the contact pair according to its initial gap or penetration and the contact detection region. A pair that is expected to transmit load but starts open … Continue reading How Interface Treatment Works in Ansys Mechanical Contact Analysis

Contact Analysis of a Pipe-clamp Assembly
We have discussed multiple examples of contact analysis so far. In this post, we are going to investigate a pipe-clamp assembly. By using a pretensioned bolt, the clamp holds the pipe firmly (see the following figure). If the pretension is insufficient, slipping would happen between the pipe and clamp. If the pretension is too large, … Continue reading Contact Analysis of a Pipe-clamp Assembly
The stress and deformation analysis of a rubber O ring
In this post, we are going to analyze the stress and deformation of a rubber O ring as shown in the following figure. The rubber O ring is often used for sealing purposes. It may be under large pressure and its deformation is constrained by the sealing groove. Due to the large difference in the … Continue reading The stress and deformation analysis of a rubber O ring
