Modeling & Simulation (Page 6)

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...

EWI has recently developed a new technique to obtain improved accuracy in material flow stress for modeling metal forming processes. The method uses the hydraulic bulge test (HBT) and digital image correlation (DIC) analysis and applies the plastic work equivalency principle to determine an optimal arc length for the for calculation of a biaxial flow...

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...
