Modeling & Simulation (Page 8)

When 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...

While 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...

EWI will present two free technical webinars in August 2021. All are invited to attend: Gaps and Gen 3 Steels, August 3, 11:00 am EDT Presented by James Cruz, Principal Engineer Generation 3 steels offer many benefits for automotive, body-in-white manufacturing, but they are also associated with cracking behaviors in resistance spot welds. In addition, the...
