Bolts serve different purposes in mechanical systems. Depending on their purpose, their number might change in the design.
For instance, in a system such as this, there are fewer bolts and it can be modeled using solid elements.
But is it efficient to model a system such as this, which has numerous bolts, using the same solid elements?
How do we decide which representation to use?
This lesson discusses the pros and cons of modeling a bolt as a solid body versus a line body. It also explains a simplified approach for bolt modeling, along with the types of bolts and their contact representation in Ansys Mechanical.
Here are the accompanying handout slides for this lesson.
