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 application of contact elements: A bolted beam-column connection
In this post, we are going to explore the application of CONTA174 (i.e. 3D 8-node face-face contact element). CONTA174 is used to represent contact and sliding between 3D target surfaces and a deformable surface defined by this element. It can be used for both pair-based contact and general contact. In the case of pair-based contact, … Continue reading The application of contact elements: A bolted beam-column connection
