Workshop: Predictive Theoretical and Computational Approaches for Additive Manufacturing; National Academy of Sciences, Washington D.C.; October 7-9, 2015

添加制造，如3D打印，使复杂的形状得以实现，否则无法制造。对这项技术的成熟度和健壮性的迫切需求迅速引发了工程界在这一领域的大量研究。专家们需要走到一起，分享添加剂制造的最新进展，并讨论理论和预测性模拟工具的进展，这些工具可以促进基于添加剂制造工艺的新材料和产品的开发。添加剂制造方法具有巨大的潜力，可以促进工程领域许多领域的变革性研究，例如先进制造、生物医学应用、材料设计、超材料和能量吸收装置设计。美国国家理论和应用力学委员会将于2015年10月7日至9日在华盛顿特区举办一次研讨会，以应对理论和计算方法方面的挑战和机遇，以整体、多方面和跨学科的方式推进加法制造。在这次会议上，来自不同部门和行业的专家将分享他们的最佳实践和想法。虽然过去曾举办过关于添加剂制造的研讨会，但这次研讨会将侧重于理论和计算方法。这些方法的准确性和可靠性为它们产生的任何建模技术的预测特性奠定了基础。这一独特的研讨会将涉及基于模拟的工程与科学、综合计算材料工程、力学、材料科学、制造工艺等专业领域。重点将是技术性的，但它也将涉及政策或与这一主题相关的其他问题。该研讨会的目标是考虑到现有的计算和理论方法以及可用的数字材料，为加法制造开发一个综合的框架或制造方法。添加剂制造工艺的理论、数学和计算方法的当前和未来趋势将通过研讨会进行彻底的调查和传播。由国家科学院任命的六名专家组成的规划委员会将准备议程并确定演讲者。预计将有40人亲自参加研讨会，其他许多人将通过网络研讨会参加。会议组织者将向研究社区提供会议的现场网络直播，并使社区能够通过基于网络的工具进行输入。

Additive manufacturing, such as 3D printing, enables the realization of complex shapes that are otherwise impossible to manufacture. The urgent need for maturity and robustness of this technology has rapidly initiated a great deal of research in this area from the engineering community. There is a need for experts to come together, to share the state-of-the-art in additive manufacturing and discuss advances in the theoretical and predictive simulation tools that can facilitate the development of new materials and products based on additive manufacturing processes. Additive manufacturing methods have great potential for promoting transformative research in many fields across the vast spectrum of engineering, e.g., advanced manufacturing, biomedical applications, materials design, meta-materials, and energy-absorbing device design. The U.S. National Committee on Theoretical and Applied Mechanics will host a workshop in Washington, DC, on October 7-9, 2015, to address the challenges and opportunities in theoretical and computational methods to advance additive manufacturing in a holistic, multifaceted, and interdisciplinary way. At this meeting, experts from different sectors and industries will share their best practices and ideas. While workshops on additive manufacturing have been held in the past, this workshop will focus on theoretical and computational approaches. The accuracy and reliability of these approaches lay the foundation for the predictive characteristics of any modeling techniques spawned from them. This unique workshop will involve such areas as simulation based engineering and science, integrated computational materials engineering, mechanics, materials science, manufacturing processes, and other specialized areas. The emphasis will be technical, but it will also address policy, or other issues related to this topic. The goal of this workshop is to develop an integrated framework or manufacturing methodology for additive manufacturing considering the computational and theoretical approaches and digital materials available. The current and future trends in theoretical, mathematical, and computational approaches for additive manufacturing processes will be thoroughly investigated and disseminated through the workshop. A planning committee of six experts appointed by the National Academies will prepare the agenda and identify the speakers. It is expected that 40 participants will attend the workshop in person and many others via webinar. The meeting organizers will provide a life webcast of the meeting to the research community and enable community input via web-based tools.
