AISI Initiates Bar Steel Fatigue Blog as New Design Tool for Automotive Engineers

Building on the success of its Bar Steel Fatigue Database, the American Iron and Steel Institute (AISI) is rolling out the Bar Steel Fatigue blog (Web log), an online tool for automotive engineers looking for the latest fatigue innovations and information.

“Now in its 10th year, the Bar Steel Fatigue Database is accessed regularly by automotive engineers, as the information and technologies are constantly evolving, providing additional time and cost efficiencies,” said David Anderson, director of AISI’s Long Products Market Development Group (LPMDG). “The blog will take this powerful tool to the next level, as it creates new opportunities for interactive collaboration with fatigue and industry experts.”

The blog is open to participation by steel and ground vehicle OEM and supplier design engineers, powertrain/chassis engineers, materials engineers, application engineers and Finite Element Analysis experts, as well as current users of the Bar Steel Fatigue Database and visitors to the AISI Automotive Web site. Topics for discussion include the comparison of the fatigue properties of high carbon steels for various processing cycles and the fatigue properties of medium carbon steels in the normalized, quenched and tempered conditions.

Web users are invited to provide feedback on the various topics and post steel fatigue questions, which will build the online forum of information. To visit the blog, go to

Blog administrator, Dr. Thomas Oakwood — one of the founding developers of the AISI Bar Steel Fatigue Database — brings more than 40 years of industry experience working in the steel and related industries. He holds a doctorate in metallurgical engineering from the University of Oklahoma.

The Bar Steel Fatigue Database was developed by the Bar Steel Fatigue Committee of AISI’s Long Products Market Development Group, which is recognized as the “number one resource group” for expertise in the automotive bar and rod steel industry. Continued outreach programs, like the blog, ensure that LPMDG member companies develop product and manufacturing technology innovations and provide technology transfer to keep steel the material of choice.

Through the support of the American Iron and Steel Institute, the Long Products Market Development Group is growing the market for value-added steel bar and rod products. With seven member companies and two task forces Automotive/Heavy Equipment and Construction/Infrastructure the group is committed to developing innovative solutions to the challenges facing their clients and the steel industry.
