THE DEVELOPMENT AND IMPLEMENTATION OF INTEGRATED COMPUTATIONAL MATERIALS ENGINEERING (ICME) FOR AEROSPACE APPLICATIONS

Considerable effort has been expended over the past three decades developing materials, processing, and behavior models. While many of these models are currently employed in the industry by both engine OEMs and their suppliers, the anticipated major benefits from the use of such models have not been realized. We believe that basic technology approaches for Integrated Computational Materials Engineering (ICME) exist and that an industry-wide plan for the development, integration, and validation of such methods would lead to their broad implementation with significant benefits to the aerospace industry and its customers. This paper presents a general overview of the current state of ICME related to the aerospace propulsion industry, and identifies key challenges and barriers to broad development and implementation.
