Residual stress plays a major role in the science and engineering of mate- rials and products, impacting the ma- the accuracy level required for many applications. Predicting residual stress requires a clear understanding of the processes used to manufacture the ma- terial, in addition to accurate and ap- propriate materials property data to describe the mechanical properties during each step of any thermomechan- ical process. To help with the latter, ASM International, along with the University Fig. 5 — Examples of common destructive and nondestructive methods to measure residual stress and typical length scales over which each method is applicable. Additionally, examples of processes that induce residual stresses and the typical length scales over which these occur. Fig. 6 — Model predictions of machining distortion for an axisymmetric disk component without prior control of bulk residual stresses (top) and for a disk where prior bulk residual stresses are optimized and specifically controlled. The predicted distortions are magnified to enable visualization and comparison. terials, manufacturing, and product de- sign communities, to name a few. These stresses can be either friend or foe, de- pending on how they are managed. Fig- ure 6 shows a schematic of machining distortion from both a nonoptimized and optimized holistic manufactur- ing process sequence. It is clear that with focused effort and greater under- standing and control of residual stress- es, machining distortion can be readily mitigated. TECHNICAL COMMITTEES INVITE VOLUNTEERS ASM is currently working to restructure the society committee infrastructure to enable increased support to and involve- ment fromASMmember volunteers. ASM has a number of long-standing content or programming committees aimed at various publication, conference, and database activities, such as the Handbook Committee, the AeroMat Organizing Committee, and the Materials Database Committee, to name a few. One current area of focus for ASM is the ability for members to come together and conduct volunteer activities in specific technical areas. ASM is establishing a formal process for members to create “virtual communities of practice” or “special inter- est groups” via the ASM Connect system or through ASM Chapter efforts. These focused technical communities can be very in- formal as they work on local Chapter projects or international efforts in a common technical area of interest. ASM technical committees can be formalized through proposals to the ASM Volunteerism Committee, which will oversee the creation, health, and sustainment of newly formed technical committees. The Residual Stress Technical Committee is an example of a group that provided a proposal to ASM regarding the formation of this committee and is now underway with sev- eral projects. After technical committees are formed, they will seek out members with similar interests to further the focused topic throughout the materials community. It is critical that ASM International technical communities link with other standing con- tent and programming committees to develop synergistic efforts, such as providing input to handbooks, books, journals, da- tabases, or conference symposia. In addition to the Residual Stress Technical Committee, there are several other technical committees that are being con- templated by ASM members, including: Material and Process Modeling Applications; Materials Data Management Tools/Meth- ods; and Additive Manufacturing Technology.
