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. Cosmological implications of a QCD-like composite Higgs model

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

   Author : Hristina Georgieva Hristova; [2021]
   Keywords : composite Higgs; technicolor; gravitational waves; LISA; phase transition; Physics and Astronomy;

   Abstract : Some of the shortcomings of the Standard Model of particle physics are the 'unnatural' value of the mass of the Higgs boson and the fact that the model cannot account for the process of baryogenesis - a mechanism which generates the observed asymmetry between matter and anti-matter in the Universe. The former is related to the fundamental scalar nature of the Higgs boson, connected to quadratic divergences in the mass corrections. READ MORE

4. 3. Assessment of hydropower mitigation measures for fish habitat rehabilitation with a coupled eco-hydraulic model : A case study on the Skålan-Äldern stretch

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Francesca Polato; [2021]
   Keywords : hydropower; mitigation measures; ecological flow assessment; hydraulic modeling; physical habitat models; vattenkraft; begränsande åtgärder; ekologisk flödesbedömning; hydraulisk modellering; fysiska livsmodeller;

   Abstract : In the past century, hydropower development in Sweden has been facilitated by the lack of appropriate environmental legislation. This exploitation has resulted in the current poor ecological status of most Swedish water bodies affected by hydropower, and in the need for new policies that reflect the 2000 European Water Framework Directive.

5. 4. Fatigue Testing of a Unidirectional Carbon Fiber Reinforced Polymer : Investigation of damage development using Digital Image Correlation

   University essay from KTH/Lättkonstruktioner

   Author : Lars Johan Wenner Berg; [2020]
   Keywords : ;

   Abstract : Carbon Fibre Reinforced Plastic (CFRP) is a material with high specific propertiesand good fatigue and vibration dampening characteristics, and can potentiallybe used instead of steel and aluminium in heavy duty vehicles. This work focuseson testing methodology and the fatigue properties of a unidirectional (UD)material in the 0° and 90°orientation, reproducing and validating the method developedby Wanner[1].

6. 5. Investigating In-plane Shear Behaviour of Uncured Unidirectional Prepreg Tapes

   University essay from KTH/Lättkonstruktioner

   Author : Ming Kai Chea; [2019]
   Keywords : ;

   Abstract : Steering of prepreg tows in an automated fibre placement (AFP) process allows geodesic layup trajectory over a doubly-curved surface, as well as the potential to improve the efficiency of composite structures by tailoring their stiffness. However, defects (such as out-of-plane buckling and tow pull off) are commonly generated when the steering radius exceeds a critical limit, which impact the mechanical properties of the finished product.
