Recent Progress in Implementation of ICME for Metallic Materials in the Airframe Industry

Integrated Computational Materials Engineering (ICME) can be applied to multiple problems in materials development within the airframe industry, but most deal with how to reduce the time from discovery to implementation. For a structural material to be considered for application on a new program, preliminary design properties must be made available. Of these, fatigue, fracture and corrosion testing require the most cost and effort, and hence, development of ICME technques to estimate values for related properties, whether from constitutive microstructural relationships, simple tensile data, or from continuum mechanics, remains a high priority. The present paper reviews progress since our 2012 AIAA paper reviewing metallic material ICME efforts, with a focus upon estimating durability and damage tolerance properties at an earlier point in the materials development cycle. Additional thoughts on progress and gaps in ICME for the aerospace business are also addressed.
