1. 1. Investigation of the basic mechanics of edge cracking in sheet aluminum forming

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Hamidreza Bayat; Mohammad Abbasi; [2023]
   Keywords : Open Hole tensile test; Digital Image Correlation; Strain Rate; Istra 4D; Thickness reduction rate;

   Abstract : As technology is developing in all automotive companies, car body designers have also investigated new materials such as composite and aluminum alloys. Designing modern car structures has also created various challenges in the production process, including formability limitations. READ MORE

3. 2. Can Dwarf Galaxies Tell Us How the Milky Way Formed?

   University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

   Author : Þóra Karlsdóttir; [2023]
   Keywords : Dwarf Galaxy; Milky Way; Physics and Astronomy;

   Abstract : Dwarf galaxies are a key component in understanding the evolution of galaxies and provide tests on the standard cosmological $\Lambda$ Cold Dark Matter model. According to the formation hierarchy, dwarf galaxies are the pieces that create all galaxies. Our current understanding of dwarf galaxies faces discrepancies between theory and observations.

4. 3. Pre-Straining Operation : Prediction of Strain Paths Within a Forming Limit Diagram

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Elin Olofsson; Mohammed Al-Fadhli; [2022]
   Keywords : Forming Limit Diagram; Forming Limit Curve; Non-Linear Strain Paths; Pre-Straining; Sheet Metal Forming.;

   Abstract : In a Sheet Metal Forming (SMF) operation, complex geometries in multi-stage forming processes are mostly common. Forming a blank, major and minor straining willoccur. Follow the straining of the blank elements over the forming process will provide its strain paths. READ MORE

5. 4. Black Hole Dynamics in Stellar Clusters

   University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Markus Strickert; [2022]
   Keywords : Black Holes; Globular Clusters; Dynamics; Intermediate-mass black holes; Simulations; Physics and Astronomy;

   Abstract : Star clusters can harbour many exotic objects, including black holes (BHs), X-ray binaries and blue straggler stars. In dense stellar environments like globular clusters (GCs), two-body relaxation drives their dynamical evolution, where gravitational interactions between stars strive to equalize their kinetic energy in the cluster.

6. 5. Elemental variability in tree-rings as indicator for climate change : a case study on beech and oak trees at the Laacher See, Germany

   University essay from Stockholms universitet/Institutionen för naturgeografi

   Author : Ann-Kathrin Wild; [2022]
   Keywords : trace elements; tree-rings; dendrochemistry; dendroclimatology; ITRAX; Laacher See; mofettes; tree-bark; Quercus sp.; Fagus sp.;

   Abstract : The aim of this study was to contribute to the comprehension of the connection of element uptake in trees at the Laacher See in Germany and climatic parameters on different time scales. Understanding the relationship of certain elements in trees and temperature might enable the assignment of extraordinary high peaks in the elemental concentration, which cannot be explained by temperature, to another process as CO2 degassing of the mofettes, which are relics of the volcanic past of the lake.
