Focus on: Structural DynamicsMany 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
NAFEMS' technical activities are coordinated by a number of specialist working groups, drawn exclusively from the NAFEMS membership.
These working groups identify areas of interest to the analysis community that require new educational materials to be developed.
With this in mind, we are seeking to form a working group that will take ownership of all aspects of Structural Dynamics Engineering Analysis and Simulation. As well as providing best practice guidance on how to undertake dynamic modelling and simulation, the Structural Dynamics Working Group is expected to have a strong focus on the integration of simulation with test.
The working group is expected to have an international reach, and should be launched in early 2018. If you are interested in participating in this group as a steering committee member or in a subgroup or would like to propose potential members/organisations that NAFEMS should seek to contact please email dynamics@nafems.org.
The NAFEMS Dynamics and Testing Working Group was borne out of the UK Dynamics Testing Agency (DTA). The original Dynamics Testing Agency was set up in the late 1980s through a collaboration between industry and the UK’s Department of Trade and Industry to disseminate best practice to the structural dynamic community. Its output was primarily biased towards the testing community not only to provide fundamental advice on how to implement effective testing, but also to inform users on the analysis and interpretation of results. One of the objectives of the original group was to bring together test and analysis to exploit the complementary aspects of each approach. Thus, Finite Element Model (FEM) reconciliation was one of the key activities of the Dynamics Testing Agency.
One of the key documents that can came out of the Dynamics Testing Agency was the "Dynamic Test Agency Handbook". The nine volumes of this publication are available for NAFEMS Members to download from the Resource Centre
A wealth of technical papers & articles have been produced for NAFEMS events and journals, and NAFEMS Members have access to a wide range of these.
We've made some of the material on this subject available for download below - some freely available, and some exclusively for NAFEMS Members.
