Modeling & Simulation (Page 6)

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...

Additive manufacturing (AM) continues to grow in popularity as manufacturing firms develop better understanding of how to extract value from the expensive process. Designers and engineers continue to add complexity into components to tip the cost/value balance in favor of AM, as well as to gain additional benefits from light weighting, reduced assembly efforts, better...
