1. 6. Evaluation of bank erosion and stability analysis along Rönne å at Ängelholm, Sweden

   Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Författare :Arnold Mate Kalimukwa; Abuzack Juma Mohamed; [2021]
   Nyckelord :HEC-RAS; BSTEM; cross section; erosion; sediment transport; deposition; bank stability; safety factor; Technology and Engineering;

   Sammanfattning : This master thesis report presents the results of evaluation of bank erosion and stability analysis along Rönne å (river) at Ängelholm, located in south-west of Sweden within Scania. The main objectives cover building a hydrodynamic model, studying parameters that define sediment transport, modelling sediment transport within the river, mapping out erosive stretches and comparing to earlier observational study conducted by Norconsult in 2013, and finally conducting analysis of bank stability in most erosive stretches.

3. 7. Performance of reinforced concrete bridges strengthened with Carbon Fiber Reinforced Polymers : Case study: Essinge Bridge over Pampaslänken

   Master-uppsats, KTH/Bro- och stålbyggnad; KTH/Jord- och bergmekanik

   Författare :Zeinab Mirzahassanagha; Eva Malo; [2021]
   Nyckelord :CFRP; External Strengthening Method; RC Bridges; Curved Substrate; Finite Element Modelling; Kolfiberväv; Extern Förstärkningsmetod; Betongarmerade broar; Konkav yta; Finita Elementa Modellering;

   Sammanfattning : This master thesis deals with the performance of existing reinforced concrete bridges strengthened with externally bonded carbon fibre reinforced polymers (CFRP). One of the main aims of this work is to understand the functionality of such an external strengthening method applied to a concave surface in a heavy concrete structure such as a bridge. LÄS MER

4. 8. Mounting of Inner Support Structure on the Swedish Warship Vasa : Product Development

   Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Författare :Camilla Granbom; [2020]
   Nyckelord :Product development; mounting;

   Sammanfattning : The master’s thesis is focused around the mounting of an inner support structure to the Swedish warship Vasa and was given by Camatec Industriteknik AB. The Swedish warship Vasa is one of the greatest national treasures of Sweden. The ship was built high and narrow, therefore a small gust of wind made her capsize during her maiden journey. LÄS MER

5. 9. Extensional Instability in Complex Fluids: A Computational Study

   Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

   Författare :Muhammed Abdulrazaq; [2020]
   Nyckelord :Complex Fluids; Computational Rheology; Elastoviscoplastic Fluids; Instability.; Komplexa vätskor; Beräkningsreologi; Elastoviskoplastiska vätskor; Instabilitet.;

   Sammanfattning : In this study, instability and failure in complex fluids (Elastoviscoplastic fluids) is explored using the classic Considère (F˙ < 0) and stress curvature (σ¨ < 0) criteria. Employing the Saramito model, numerical simulation of the extensional protocol on non-Newtonian fluids is carried out. LÄS MER

7. 10. Mechanical properties of SiC nanowires with polytypes

   Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Författare :Anders Vesti; [2019]
   Nyckelord :atomistic modeling; nanowires; molecular dynamics; simulation; SiC; silicon carbide; fracture behavior; nanomechanics; Physics and Astronomy;

   Sammanfattning : In this report, we model the mechanical properties and fracture behavior of SiC nanowires with different polytypes using Molecular Dynamics (MD) simulations. The mechanical properties investigated are the Young’s modulus, the maximum tensile stress and the fracture strain. The three polytype tested are SiC (3C), (2H) and (4H). LÄS MER
