Abstract
Sheet metal bending is one of the most common operations in metalworking. However, bending still presents key design factors not fully understood like punch load predictions. This article models the punch-die bending of a sheet metal piece using finite element approach. It provides some insights on the stresses distributions during the operation. It investigates bending forces comparing it to the empirical design formulas. It also discuss some parameters affecting the bending operation on a V-die
