Abstract
Integrated Computational Materials Engineering (ICME) is a transformational discipline for improving national security. ICME has been defined as the "capture of materials information in computational tools that link manufacturing simulation and product performance analysis". This can be used to significantly reduced product development costs and accelerate the time to design and develop new materials and engineering components and systems. There is a desire to develop and implement an integrated ICME capability Naval Ship Warfare Center - Carderock (NSWC) and Naval Research Laboratory (NRL) with the initial application to be on ICME for Additive Manufacturing of structural metallic components. We propose to assist the US Navy in development and implementation of such an ICME capability. The primary aim of this proposed work is the development of an ICME Module for predicting the mechanical properties, such as fatigue properties, of 316 stainless steel formed via additive manufacturing. This will involve use of ultrasonic fatigue for rapid assessment of processing effects on defects and development of a small crack fatigue crack growth model for predicting high cycle fatigue resistance of additive manufactured 316 stainless steel. The PRISMS-Plasticity crystal plasticity finite element model will be calibrated for additively manufactured 316 stainless steel and used in development of property models. In addition, we will assist in developing and implementing a state-of-art ICME Infrastructure for the US Navy, including software and materials information infrastructure.
