Efficient force prediction for incremental sheet forming and experimental validation

摘要: Incremental sheet forming (ISF) has been attractive during the last decades because of its greater flexibility, increased formability and reduced forces. However, traditional finite element simulation used for force prediction is significantly time consuming. This study aims to provide an efficient analytical model tangential prediction. In present work, forces cone-forming process with different wall angles step-down sizes are recorded experimentally. Different trends identified discussed reference deformation mechanisms.
