    About the Event

    Papers are invited for a Second Symposium on Fatigue and Fracture of Additively Manufactured Materials and Components to be held Wednesday – Friday, November 18-20, 2020. Sponsored by ASTM Committee E08 on Fatigue and Fracture, the symposium will be held at the Renaissance Orlando at SeaWorld in Orlando, FL, in conjunction with the November standards development meetings of the committee.

    Having been established in the early 80’s, Additive Manufactured (AM) processing of materials is not an infant technology. It is, however, the latest panacea for rapidly producing a bevy of ground vehicle, aerospace, medical device, and other such components. This technology has advanced from the early stereolithographic photopolymer processes to selective laser sintering and the later electron beam direct metal fabrication of essentially fully dense components from a variety of metals, ceramics, and polymers.

    Herein lays the caveat of “essentially fully dense” and the influence of, for example, internal microdiscontinuities on the dynamic fatigue and fracture resistance of AM materials and components to duty cycles of deformations, forces, stress, strain, and complex multiaxial histories. Additively manufactured materials and components often also exhibit microstructural variations based on build orientation and section thickness and contain build induced residual stresses. As a result, the fatigue and fracture behavior of component produced using the various AM processes are not fully characterized and understood. For these reasons, ASTM Committee E08 on Fatigue and Fracture will provide a forum for the Second Symposium on Fatigue and Fracture of Additive Manufactured Materials with the following aspects and effects to be considered and discussed:

    • Applicability of existing fatigue and fracture test methods to AM materials
    • Development of new fatigue and fracture test methods and/or specimens for AM materials
    • Fatigue and fracture behavior of components fabricated using AM
    • Residual stress effects
    • Effects of process and design parameters on fatigue and fracture behavior
    • Process optimization to improve fatigue performance of AM materials
    • Nondestructive evaluation of components fabricated using AM
    • Characterization of internal microdiscontinuities
    • Correlation between component and test specimen behavior
    • Effect of surface quality and finish
    • Build direction and layer orientation microstructure variation and anisotropy
    • Component volumetric and size influences
    • Effect of post processing (including HIP) on fatigue and fracture properties
    • Statistical nature of fatigue and fracture processes for AM components
    • AM build simulation and damage analysis techniques
    • Multiaxial deformation and loading of AM components

    The application of existing and potentially the development of new fatigue and fracture ASTM Standards to this breed of AM materials is to be addressed and discussed.

    The language of the symposium will be English.


    Abstract Submittal

    To participate in the symposium, authors must submit a 250 to 300-word preliminary abstract using the online Abstract Submittal Form no later than February 28, 2020. The form can be accessed by scrolling to the top of the page and clicking “Go to Abstract Submittal Form”. To ensure your abstract was received into the ASTM database, please email symposia@astm.org and let us know that you have submitted an abstract.

    The abstract must include a clear definition of the objective and approach of the work discussed, pointing out material that is new, and present sufficient details regarding results. The presentation and manuscript must not be of a commercial nature nor can it have been previously published. Because a limited number of abstracts will be accepted, be sure that the abstract is complete to allow for careful assessment of the paper's suitability for this symposium. Symposium Chairs will notify you via postal mail no later than April 30, 2020 of your paper’s acceptability for presentation at the symposium. If the preliminary abstract is accepted, the presenter/author will be requested to submit a final camera-ready abstract several months before the symposium. The final abstracts will be distributed in an abstract booklet at the symposium.


    Publication

    Symposium presenters are required to submit their papers to the Selected Technical Papers (STP), an online and printed, peer-reviewed publication for the international scientific and engineering community. After the final selection of abstracts has been approved, the ASTM Editorial Office will send authors’ instructions via email only. Manuscripts to be peer reviewed for the STP are due online no later than October 31, 2020 at the ASTM Editorial Office. The corresponding author (the author who is the main contact with ASTM Headquarters) will receive a copy of his/her paper in portable document format (PDF). All published authors will have the opportunity to purchase reprints of their papers at a nominal cost. Only those papers submitted by the manuscript due date will be included in the STP.

    Please note that all submitted papers are subject to single blind peer review and will be submitted to the Library of Congress with an ISBN number and will be reviewed for inclusion in the "Web of Science Conference Proceedings Citation Index" (CPCI) and Google Scholar.
