Development of Aerospace Materials Using Integrated Numerical and Physical Simulation

摘要

The introduction of new alloys and process improvements that promise increased material performance to the aerospace and defense industries is a long and costly venture due to ensuring flight safety by way of data analysis and field service. Changes to the supply chain require the use of a phased approach, typically technical readiness level (TRL), to reduce risk. The techniques in the TRL methodology include both physical simulation, such as demonstrators, and computational simulation within the Integrated Computational Materials Engineering (ICME) framework. The typical approach consists of designing a methodology using computational processing, conducting pilot-scale trials, and using a TRL approach for scaling the technology. A balanced combination of physical and numerical simulations aids in understanding the role of metalworking processes in microstructure and property development. This in turn ensures the development of new and improved products in an accelerated manner. This paper reviews simulation methods, both computational and physical, available in the metals industry and discusses examples of how the use has accelerated deployment of new products.
