1. 1. Exploring the Possibilities of Sheet Metal Forming Via Plastic-Based Additive Manufacturing Moulding

   University essay from KTH/Produktionsutveckling

   Author : Jemal Idris Ismail; Kafeel Olanrewaju Sanni; [2023]
   Keywords : : Sheet metal formation; Additive manufacturing; mass customization; personalized production; die design; die system; FDM; DOE; FEA; product development; automotive; sustainability; cost effective; metal dies; plastic dies.; Plåtformning; Additiv tillverkning; massanpassning; personlig produktion; formdesign; formsystem; FDM; DOE; FEA; produktutveckling; fordonsindustri; hållbarhet; kostnadseffektiv; metallformar; plastformar.;

   Abstract : Additive Manufacturing (AM) has freeform fabrication capabilities of complex geometries directly from feedstock material. This can potentially enhance the efficient use of material and the cost effectiveness. It also offers design flexibility, and it is versatile. READ MORE

3. 2. Non-Linear strain paths in Sheet Metal Forming

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Anton Eriksson; [2021]
   Keywords : Sheet metal forming SMF ; Non-Linear strain path NLSP ; Test procedures; Failure models; Finite Element FE ; Plåtformning; Icke-linjära töjningsbanor; Test procedurer; brott model; Finita Element FE .;

   Abstract : Today's automotive requirements have resulted in complex Sheet Metal Forming (SMF) processes of Sheet Metal (SM) with reduced formability, and thus it is crucial to be able to predict formability accurately to prevent material failure during SMF. Formability predictions today utilize Forming Limit Curves (FLC)s in Finite Element Analysis (FEA), but  FLCs are not valid for the Non-Linear Strain Paths (NLSP)s generated during SMF. READ MORE

4. 3. Extraction of tool reaction forces using LS-DYNA and its use in Autoform sheet metal forming simulation

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Esbjörn Zachén; [2019]
   Keywords : Sheet Metal Forming; Stamping Die; blank holder; Structural Analysis; Finite Element Simulation;

   Abstract : In product development there is still potential to decrease lead times with faster and more accurate simulations. The objective of this thesis was to study whether Finite Element (FE) simulations using explicit LS-DYNA to extract reaction forces from sheet metal forming tools during forming, could be used to improve existing FE models in sheet metal forming software AutoForm.

5. 4. AP&T Machine and Line Usability : A usability analysis of stand-alone machines and production lines at AP&T

   University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

   Author : Fanny Åkerström; [2019]
   Keywords : Usability; user experience; user needs; human-machine interaction; press hardening; industry; digitalization; automation; production solution; development; Användarvänlighet; användarupplevelse; användarbehov; HMI; presshärdning; industri; digitalisering; automation; produktionslösning; utveckling;

   Abstract : Automation and digitalization are developing at a high pace and it is important to keep the focus on human-machine interaction. It is becoming more and more important that the usability in machines and lines is related to the development so that the performance and availability of the production processes in the industry are not adversely affected.

6. 5. Sheet Metal Forming Simulations with Elastic Dies: Emphasis on Computational Cost

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Sara Allesson; [2019]
   Keywords : Elastic Sheet Metal Forming Simulation; Computational Cost; Decomposition; LS-DYNA; Elastisk plåtformningssimulering; beräkningskostnad; dekomposition; LS-DYNA;

   Abstract : The car industry produces many of their car parts by using sheet metal forming, where one of the most time-consuming phases is the development and manufacturing of new forming tools. As of today, when a new tool is to be evaluated in terms of usability, a forming simulation is conducted to predict possible failures before manufacturing. READ MORE
