"The committee believes that the MSE discipline is at a critical crossroad and that computationally driven development . . . can be a core activity of materials professionals in the upcoming decades."
—Committee on Integrated Computational Materials Engineering
Integrated Computational Materials Engineering, or ICME, is an emerging discipline that was recently the subject of a National Materials Advisory Board (NMAB) study, an excerpt from which is quoted above (see Reference 1). TMS has been a leader in facilitating the development of this area and is in fact recognized in the recently released report for these efforts. TMS, too, is at a crossroad in determining our role in aiding further growth of ICME. In this month's edition of "Presidential Perspective," I am soliciting your inputs as we consider how to move ahead.
First, let me provide some context and background. ICME is an overarching approach to bridge length and time scales in computational materials science and engineering, with multiscale modeling and materials informatics being two other important approaches being actively pursued. There are many similarities between ICME and multiscale modeling, with much of the progress to date in multiscale modeling providing a good basis for ICME techniques. Typically, ICME has had an engineering focus while multiscale modeling efforts have largely been science focused. Materials informatics is much more data focused.
TMS AND ICME
Recent TMS efforts have recognized the importance of all approaches to spanning length and time scales, with ICME coverage at the TMS Annual Meeting and in JOM including aspects of Materials Informatics and Multiscale Modeling.
How did these events within TMS begin? In late 2005, the TMS Board of Directors commissioned the Integrated Computational Materials Engineering Technical Advisory Group, or ICME TAG, under the leadership of TMS Past President John Allison. The charge of the ad hoc ICME TAG was to provide recommendations to the TMS Board of Directors along with Technical Divisions and Committees for incorporation in the TMS Strategic Plan and execution of key initiatives.
The TAG recognized that TMS is well positioned to take a leading role in advancing ICME for the benefit of its members and the materials profession. This is because:
In February 2006, the ICME TAG made several recommendations to the TMS Board of Directors. Specifically, the group recommended that TMS establish a Technology Coordination Group for ICME (ICME TCG); develop an integrated three-year plan for information dissemination on ICME; become the professional home for the ICME community; facilitate educational development in ICME; and facilitate technical development of ICME.
In the past two years, significant activity in the ICME area has been underway at TMS. Here is a summary in a few categories.
TMS 2007 Annual Meeting symposia included:
TMS 2008 Annual Meeting symposia included:
Publication in JOM
In November 2006, JOM presented a series of papers on ICME. In 2008, the journal is planning a two-part series on materials informatics. In March, JOM presented part one, a series of articles that provided a broad look at materials informatics. In December, a second series of articles targeting specific materials science platforms is planned.
At the TMS 2007 Annual Meeting, TMS launched the ICME community as one of the first six pilot on-line communities of practice as part of the Materials Technology@TMS initiative (http://materialstechnology.tms.org/icme/icmeHome.asp).
THE NMAB REPORT
Of course, another important activity that was underway was the formation of the NMAB committee on ICME. This committee was chaired by TMS Past President Tresa Pollock with Allison acting as vice chair and included many active TMS members. It is the completion of the committee's work and publication of their findings and recommendations that serves as the catalyst for this article. The report is available from the National Academies at http://www.nap.edu/catalog/12199.html as a free pdf or hard copy for purchase.
The NMAB ICME report does an excellent job of detailing the state of development of ICME, including its application in a range of areas including automotive and aerospace applications. It highlights the roles of industry, government, universities, and professional societies in advancing the area, as many reports of this type do. In my opinion, the report also goes beyond these more typical findings and recommendations in a very significant way. As the title of the report suggests, the committee sees ICME as a "transformational discipline." In fact, and to quote again from the report itself:
"For ICME to succeed, it must be embraced as a discipline by the materials science and engineering community, leading to requisite changes in education, research, and information sharing. . . . [This would] transform the role of the field of Materials Science and Engineering to one of uniting engineering and scientific endeavors into more holistic and integrated activities." (Reference 2)
As an educator and one who has been involved in the field for over three decades, I believe that, as a natural evolution of computational MSE, ICME can truly transform the way materials science and engineering is learned and practiced. There are many curricular as well as pedagogical issues that need to be considered and acted upon. Accolades to the NMAB committee for a job well done; the report provides us with a vista for the future that is compelling and exciting.
The NMAB committee recognizes that professional societies like TMS will play an important role in this vision. According to the report, professional materials societies should foster the development of ICME standards and collaborative networks, support ICME-focused programming and publications, and provide continuing ICME education. These issues will be part of this summer's strategic planning discussion, as the TMS Board of Directors looks at the role of TMS in serving the broadening MSE community.
Again, I encourage you to add your voice to the discussion. I have framed some questions to start the dialogue in this discussion forum. I look forward to your point of view.
