Numerical simulation analyses of metal forming processes involve a high level of complexity, from both fundamental and industrial application standpoints, requiring robust and comprehensive technology in order to achieve realistic solutions. Focusing on advanced models for numerical simulation based on the Finite Element Method and Meshless Formulations, this Minisymposium aims to present and discuss the current state of the art as well the challenges in the computer-based engineering analysis of conventional and innovative material forming industrial processes, trying to establish guidelines for future research in this field of computational mechanics. Typical metal forming techniques to be analysed include sheet and bulk forming, extrusion, tubular and open-blank hydroforming, electromagnetic forming, incremental sheet forming, friction stir welding and conventional joining operations, among others. A special focus will be put on sources of nonlinearities prone to affect the accuracy and reliabilities of numerical approaches (locking effects, hourglass instabilities, fluid-structure iterations, thermal-mechanical coupling, contact and friction, anisotropic constitutive criteria and hardening mechanisms, among other), thus promoting communications between academic and industrial researchers. In this sense, this Minisymposium intends to be a strong contribution in achieving better solutions for realistic forming problems, at the same time trying to establish a bridge between the academic and industrial worlds. Doing so, the main goal is to promote the debate between researchers involved in numerical simulations, in order to set the major lines of developments for the near future.
