Modelling Bolt Pretension

How to model bolt pretension in ANSYS Explicit Dynamics?

In many of the Engineering situations, bolted connections are commonly used for connecting two or more parts together. In many such situations, the pretension of the bolt can significantly impact the solution accuracy. Explore the solution file to learn how to setup a generic Explicit Dynamics model which demonstrates how bolt prestressing can be modelled in conjunction with a drop test.
