As most structures involve some sort of jointing or connection, often running into many thousands, or even millions of connections in one individual body, the analyses involved can be among the most difficult an engineer can face. As you can imagine, there has been a significant amount of activity within NAFEMS around these issues, and we've collected some of the resulting information here.
Many of the resources below are available free for you to download, with others accessible exclusively to NAFEMS Members, e-library subscribers, or to buy directly from our website.
We hope you find this brief update useful. If you have any comments, or thoughts on future areas that you'd like to see us focus on in the future, please get in touch at focus@nafems.org
This extract from the NAFEMS Advanced Workbook of Examples summarises several aspects of the modelling of bonded joints, and is free to download below. You can also download the entire publication from the e-library, or buy the book.
In October 2003, NAFEMS began to publish a series of articles in benchmark magazine, aimed at covering a number of basic FEA principals in a readable and useful format. This “knowledge base” series continued to run over the next seven years, based on the principal that it is always useful to reinforce basic concepts and theories, no matter how advanced the user of the technology has become.
This short article on the analysis of fabricated structures, is free to download at the link below.
NAFEMS members have access to the full series here, and the book can be purchased here
NAFEMS events provide the engineering analysis community with invaluable opportunities to learn, network and present. We've collected some of the presentations on this topic together, and made them available for download below
Challenges in Developing a Generalized Idealized Fasterner Method NAFEMS Americas Conference 2016
| Influence of Contacts on Lug Joint Internal Loads & Safety Margin within Assemblies Seminar - Engineering Analysis & Simulation in the Aerospace Industry
| Water Tightness of Polyethylene Flange Joints NAFEMS Nordic Conference 2016
|
An Introduction to the Dynamics of Joints Workshop - Dynamics of Joints | Techniques for modelling joints: A review of Static Design Approaches Workshop - Dynamics of Joints |
This 3-session, live online course covers a range of topics, all aimed at structural designers and engineers. The objective of this course is to review the various connection and joint technologies in use, give an overview of the physics involved and show how to successfully implement practical solutions using Finite Element Analysis.
Find out when is the next run of this course:
This document provides a synopsis of a NAFEMS seminar on Idealisation of Joints held in Wiesbaden, Germany, in April 2010 including a summary of the industry sectors that presented information, the scope of information presented and copies of papers presented.
The NAFEMS World Congress (NWC) is the only major international event dedicated to your community and your technology. Every aspect of analysis, modelling and simulation is addressed, covering numerous industries globally. There’s nothing quite like it.
We've made a selection of NWC papers on composites from previous events available to download below
NWC19 took place in Quebec City, Canada, in June 2019. Visit nafems.org/congress for full details.
