In 1992 the National Transportation Safety Board (NTSB) commissioned a report to study the causes of wheel separations from medium and heavy duty trucks. The report showed that on average between 750 ...

Bolt preload isn’t just about tightening—it’s the hidden force that keeps joints secure, leak-free, and fatigue-resistant. Engineers know that too little or too much torque can cause failure, so ...

Gasketed bolted flange joints continue to be a critical component in a wide variety of industrial applications, ranging from pressure vessels to large-scale piping systems. The analysis and ...

Bolted joint tightening mechanics is a critical field of research that elucidates the complex interplay between the applied torque and the resultant preload in bolted connections. Contemporary studies ...

From the buildings we work in, the data centers we depend on, and especially in the machines we design, we inevitably rely on bolted joint connections. Unfortunately, due to the perceived simplicity ...
