ICME

Integrated computational materials engineering (ICME) uses analytical and numerical tools to create predictive models. Recently, EWI has published a series of papers examining analytical methods that work well in assessing thermal/mechanical responses in specific joining processes. Some highly complex joining applications, however, require advanced computational tools such as finite element analysis (FEA) to achieve desired...

Common aerospace materials such as high-nickel alloys (such as René 80) or high-strength aluminum alloys (6000 and 7000 series) are not currently manufactured using additive manufacturing (AM) due to hot cracking.  As part of a $5M Department of Energy program, EWI, GE Research, and the University of South Carolina developed a model to predict and...

Integrated computational materials engineering (ICME) can be used effectively to understand thermal excursions and mechanical response in single-shot joining methods such as resistance-spot, flash-butt, friction, hot-gas, and thermite welding. As part of EWI’s ongoing series of papers examining the uses of ICME as a prediction tool in manufacturing, Senior Technology Leader Jerry Gould has written...
