As composite materials are used more extensively in structural applications, some test methods that once were considered very specialized and, therefore, not widely used, have become more significant.

In my previous column, I discussed double-shear testing of a single fastener (see “Editor's Picks,” at right). But fasteners also can be subjected to single-shear loading — our subject this time — and ...

Recent expert guidance highlights that in automotive and structural applications, the strongest fasteners are not always the safest or most effective. Engineers design some bolts, such as shear bolts, ...

The stronger the bolt, the safer the car, right? Not necessarily, as some bolts are deliberately engineered as weak points ...

Jointing is a basic function of engineering. For example, bolting two parts together can involve material properties and loading forces. Here, we will focus on preloading, shear and tear-out in a ...

This file type includes high resolution graphics and schematics when applicable. The Boeing Company’s 747 includes over 6 million parts, half of which are fasteners. Aerospace fasteners follow strict ...
