Manufacturing strategies in the 21st century are driven by the need to bring new and differentiated products to market at increasingly accelerated rates. Newer designs, application of advanced materials, and reduced development times propel manufacturers to employ innovative approaches for characterizing performance. To this end, integrated computational materials engineering (ICME), an analytical framework used to […]
Read MoreIntegrated 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 […]

Read MoreFour EWI associates have co-authored chapters in POWER ULTRASONICS: APPLICATIONS OF HIGH-INTENSITY ULTRASOUND, 2nd Edition, edited by Juan Gallego-Juarez, Karl Graff, and Margaret Lucas: Lindsey Lindamood and Mitch Matheny contributed to Chapter 10, “Ultrasonic Welding of Metals.” Miranda Marcus was a co-author on Chapter 11, “Ultrasonic Welding of Plastics and Polymeric Composites.” Amin Moghaddas co-wrote […]
Read MoreAddressing the Transmission, Distribution, and End-Use Hydrogen Systems Challenges With the emergence of hydrogen as a zero-carbon energy source, it’s increasingly important to understand the effects of high-H2 environments on materials like steel. EWI is here to support companies in their decarbonization efforts by providing materials testing and evaluation solutions, as well as ongoing research. […]
Read MoreWhat impact does the presence of H2 have on a pipe weld, and what kind of damage can result from it? These are important questions that must be answered as development of a broad hydrogen infrastructure is progressing. The EWI structural integrity group has created a new modeling approach to examine the hydrogen diffusion into […]

The live presentation will take place at 2:00 pm BST. For online […]
Read MoreWhen it comes to joining dissimilar materials in lithium-ion batteries, ultrasonic metal welding is fast and efficient. However, due to tool wear, the sonotrodes used in battery joining have to be completely replaced frequently. EWI has developed a new design approach that uses finite element analysis (FEA) to evaluate ultrasonic welding tools with replaceable knurl […]
Read MoreWhile spot weld performance has become easy to simulate in recent years, failure models for arc-welded sheet steel have never proved very reliable. Recently, EWI developed and tested a new approach to modeling failure of arc welds used in sheet-steel construction. The work is described in a paper by EWI associates Bill Mohr and Amin […]
