What is bolted joint analysis?

The bolted joint is among the most common joining methods — other common joining methods include riveting, welding, press fits, pins, keys, and adhesives. The primary components of a bolted joint include the threaded fastener as well as the parts to be joined together (the clamped parts).

What is a bolt shank?

The shank is the threadless part of the bolt between the head and thread. There are two main ways of using the shank of the bolt. One is to make the shank increase the shearing capacity.

What is frictionless contact in Ansys?

Frictionless



A zero coefficient of friction is assumed, thus allowing free sliding. The model should be well constrained when using this contact setting.

What is fixed support in Ansys?

Fixed Support fixes the part from the selected geometrical features such as faces or surfaces. It gives restraint to the part to lower the degrees of freedom of part in ANSYS® Mechanical.

Why bolts are preloaded?

Bolt preload ultimately allows a fully tightened bolt to survive in an application where an untightened or loose assembly would fail very quickly. When tight, the joint provides a conduit for the force to flow through into the assembly materials themselves.

What is a pretensioned joint?

Pretensioned A pretensioned joint is a joint that transmits shear and/ or tensile loads in which the bolts have been installed to provide a pretension in the installed bolt. Bolts can be pretensioned using turn-of-nut, calibrated wrench, twist- off-type tension-control bolt or direct-tension-indicating washer methods.

How do bolt nuts work?

Nuts and bolts are designed to hold two or more objects together. They work by inserting a bolt through the two objects and then fastening a nut at the other end of the bolt.

What are the basic components of bolted joints?

A bolted joint is one of the most common elements in construction and machine design. It consist of a male threaded fastener that captures and joins other parts, secured with a matching female screw thread. There are two main types of bolted joint designs: tension joints and shear joints.
