Using FEA as an ICME Tool to Predict the Performance of Structures
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 desiredRead more
Accelerating Production of Large Structures and Systems (RAPLSS): Establishing a National Manufacturing Roadmap
Staying competitive in large-structure production is vital for American industries today. The Accelerating Production of Large Structures and Systems (RAPLSS) survey initiative, sponsored by NIST Manufacturing USA and managed by EWI, aims to streamline this process. The Need for Large Structure Production 4.0 Technologies US industries must adopt leading-edge technologies for large structure production 4.0Read more

Predicting and Avoiding Crack Formation in Directed Energy Deposition
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 andRead more
Using ICME to Predict Thermal Response in Single-shot Welding Processes
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 writtenRead more
When Smaller is Better: EWI’S Microjoining Capabilities
Microjoining encompasses techniques including welding, brazing, soldering, and adhesive bonding. Typically, the technology involves materials with thicknesses less than 0.5 mm. Micro-welding techniques can be applied to join both similar and dissimilar materials combinations. Here are some key applications of microjoining today: Power electronics for electric vehicles (EVs). The integration of small-scale components, such asRead more
