  1. 21. Press Measurements and Virtual Rework of Stamping Dies

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Einar Palsson; Mårten Hansson; [2017]
    Keywords : Virtual Rework; Inverse Modeling; ARAMIS Digital Image Correlation DIC ;

    Abstract : Stamping dies are used in the Sheet Metal Forming (SMF) process for manufacturing of car body parts. The lead time for design and manufacturing of a stamping die is long, and therefore costly. READ MORE

  3. 22. Fracture prediction of stretched shear cut edges in sheets made of Dual-Phase steel

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Johannes Falk; [2017]
    Keywords : Strain; DP steel; Dual-phase steel; Autoform; Aramis; Fracture strain; Advanced High Strength Steels; AHSS; Fracture prediction;

    Abstract : Dual-Phase (DP) steels, part of the group of Advanced High Strength Steels (AHSS), are used by car manufactures due to its large strength to weight ratio. The high strength of the DP steel does have a negative impact on the formability during sheet metal forming and stretch forming, e.g. READ MORE

  4. 23. Integrated Blankholder Plate for Double Action Stamping Die

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Sravan Tatipala; Nikshep Reddy Suddapalli; [2016]
    Keywords : Finite Element analysis; Optimization; Sheet metal forming.;

    Abstract : A blankholder is used to hold the edges of metal sheet while it is being formed by a matrix and a punch. An efficient way to design a stamping die is to integrate the blankholder plate into the die structure. This would eliminate the time and cost to manufacture blankholder plates. The integrated structure is called integrated blankholder. READ MORE
