In last week's blog, we discussed the science behind bolted connections. Specifically their response when subjected to a combined external load and preload. In this blog we'll work through the application of bolted joint science in a finite element analysis. We will: Provide an introduction to FEA modeling of pre-loaded bolted joints, discuss some common troubleshooting techniques, establish methods to validate results of the FEA model and highlight differences between bolted joint science and real-world application.

You can see them just about everywhere you look. From massive structural steel joints that make up the Golden Gate Bridge to the intricate inner workings of an antique swiss watch, bolted connections dominate our world. Let's take a closer look at the actual science behind the bolted connection.
Process systems are getting more and more complex, and operators are demanding increased reliability. The increased complexity and reliability needs have to be balanced by budget constraints. In this blog, we go over some of the benefits of using skid systems for your applications.
Engineering doesn’t just take place at your desk anymore. Whether it’s in meetings, in the field, or on the road, you have work to do. That’s why we’ve listed the top 5 apps for that engineers should have.
Back in December of 2015, the Nuclear Industry kicked off an initiative called Delivering the Nuclear Promise. Headed by NEI and industry leaders, the goal is to help reduce operating costs. Nuclear plants have felt the pinch from low electricity prices due to the natural gas glut, and this spending cut isn't a second too late.
Sometimes the hardest part of a project is answering the question “What is it?” and the immediate follow-up “What is the governing code?” The governing code and its requirements can have a big impact on project cost and project success.
Putting in the simplest form, analysis is just the simplification of real world to an engineer, with a measure of how much assumption is put in the analysis process. Lesser the assumptions; more accurate and close is the result to real world situation. However, stress analysis, in actual practices and from technical perspective isn’t just as easy as it is to write.
Using structural shell elements in finite element analyses saves computational time when analyzing thin-walled parts and structures. But engineers and analysts require experience to best utilize the output. Unlike solid elements, where stresses are typically straightforward to understand, the analyst must be even more careful and be mindful of several questions when interpreting shell element stresses.
Spare parts management is a complicated, laborious - but critically important - aspect of nuclear plant operation. Ensuring that the right part is available at the right time and the right place requires detailed inventory management, diligent quality control, exacting acceptance testing, etc. 3D Printing to the Rescue!
When engineers think of fasteners, they usually think along traditional lines: screws, nuts, bolts, cotter pins and washers, rivets, etc. But if these same engineers are tasked with reducing costs, they look outside of their comfort zone for a fastener that will do the job and meet their reduction targets.
