2015 AAAS Annual Meeting (12-16 February 2015)

Integrated Computational Materials Engineering Principles for Additive Manufacturing

Innovation, information, and imaging are integral parts of the emerging discipline known as integrated computational materials engineering (ICME). The ICME methodologies focus on accelerating discovery, design, and deployment of advanced materials and manufacturing by integrating computational models in different length scales. This symposium will focus on the impact of ICME tools towards design, processing, and performance of structures fabricated through additive manufacturing and include viewpoints of researchers from academia, national labs, and small businesses. The notion of design complexity in engineered structures, without any penalty, will be validated. Informational overload of materials design considering metals, polymers, ceramics, glasses, and elastomers, and their atomic arrangements, volume fraction, grain size, and shape, while satisfying chemistry compatibility and maximizing mechanical properties, will be highlighted. The goal of achieving process variables that satisfy the target properties and minimization of time and cost, without trial and error experiments, will be discussed. Models of geometric, materials, and process designs must be verified and validated with ex situ and in situ characterization tools. The session will discuss the complexity of global optimization of additive manufacturing, in consideration of heterogeneity and its influence on uncertainty of performance and reliability of structures.
