Harnessing the Power of Finite Element Analysis Part 2: Structural Analysis By Amin Moghaddas Structural analysis is a critical component of Finite Element Analysis (FEA) that focuses on assessing the performance of structures under various loads and conditions. It allows engineers to refine designs, reduce material usage, and enhance performance while minimizing the need for […]
Read MoreUltrasonic metal welding is one of the most effective ways to join lithium-ion batteries. However, the need to completely replace the sonotrode due to tool wear is a limiting factor for manufacturers who are performing tens of thousands of welds per day. EWI has designed and validated a sonotrode with a replaceable tip made of […]
Read MoreHarnessing the Power of FEA Part 1: Introducing Finite Element Analysis By Amin Moghaddas Finite Element Analysis (FEA) is a powerful numerical method used to solve complex engineering problems, particularly those involving intricate geometries, loadings, and material properties where analytical solutions may not be feasible. By breaking down complex systems into smaller elements, FEA allows […]
Read MoreUltrasonic wire bonding (UWB), today’s preferred method for joining wires to battery packs in electric vehicles, requires very high surface cleanliness to assure successful bonds. Decontaminating battery terminals, however, can be a very difficult and time-consuming task. EWI has recently completed a study using laser cleaning technology on batteries prior to UWB of aluminum wire […]
Read MoreManufacturing 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 […]
