Isogeometric shell analysis of incremental sheet forming

Abstract

This thesis investigates the applicability and beneficiality of isogeometric analysis to the incremental sheet forming simulations. Incremental sheet forming (ISF) is a manufacturing process for sheet metals where the final shape is obtained incrementally using a blunt moving tool. ISF is a relatively slow process but does not need precise and expensive dies (which require a long lead time) in contrast to many other sheet forming processes. This makes it ideal for rapid prototyping, customized parts, and
