title = "Lightweighting Through Stiffening Dart Formation and Its Rigidity Evaluation",
abstract = "Stiffening darts are commonly added in angle brackets to enhance the bending stiffness of the components such that a thinner gauge can be used for lightweighting. It also helps to reduce springback in a press brake operation. This study investigates the plastic material deformation in stiffening dart formation in a press brake bending process by means of a combined numerical and experimental approach. The forming process is simulated with the finite element (FE) method and the simulation result is compared with an actual forming result to validate the accuracy of the simulation model. In addition, methods of systematically evaluating dart stiffening effect in an angle bracket are proposed, where flattening and folding tests are described. Example rigidity test results for dart designs are provided to discuss the relationship between dart geometry and its stiffening effect.",
