Workshop Statement of Task

An ad hoc committee will convene a series of three 2-day public workshops to discuss issues in defense materials, manufacturing and infrastructure including: (1) Globalization of Defense Materials and Manufacturing; (2) Big Data in Materials Research and Development; and (3) Materials State Awareness. The committee will develop the agendas for the workshops, select and invite speakers and discussants, and moderate the discussions. The workshops will use a mix of individual presentations, panels, and question-and-answer sessions to develop an understanding of the relevant issues. The workshop topics will highlight some recent developments in the fields. Key stakeholders will be identified and invited to participate. Individually-authored workshop summaries will be prepared separately by a designated rapporteur after each workshop in this series.

Materials state awareness seeks to quantify the current state of a material and/or damage with statistical metrics of accuracy located in individual systems, structures, or components, and is the heart of condition-based maintenance strategies. In principle, such quantitative evaluation should be based on knowledge of the initial state, damage or failure processes, operational environment, and nondestructive evaluation (NDE) assessment of state. However, most frequently the initial state is not known and the assessment must be done from an unknown reference state. Achieving this goal requires the integration of information from a variety of disciplines, including the mechanics of materials, materials science, engineering mechanics, and NDE engineering. Data interpretation and analysis will play a key role, including the integration of advanced analytics and statistical

measures of accuracy and precision. This workshop on materials state awareness will focus around three topics:

Topic 1: Advances in Metrology and Experimental Methods

Topic 2: Advances in Physics Based Models for Assessment

Topic 3: Advances in Databases and Diagnostic Technologies

In August 2014, the committee on Defense Materials Manufacturing and Infrastructure convened a workshop to discuss issues related to applying materials state awareness to condition-based maintenance and system life cycle management. The workshop was structured around three focal topics: (1) advances in metrology and experimental methods, (2) advances in physics-based models for assessment, and (3) advances in databases and diagnostic technologies. This report summarizes the discussions and presentations from this workshop.
