1. 1. Tomography-based Micromechanical Analysis of Novel Composite Material

   University essay from KTH/Hållfasthetslära

   Author : Mattias Grankvist; [2023]
   Keywords : paper mechanics; micro mechanics; numerical analysis; tomography; foam forming; density profile; pappersmekanik; mikromekanik; numerisk analys; tomografi; skumformning; densitetsprofil;

   Abstract : This study explores the performance of porous Paptic paper materials composed of a mixture of softwood and lyocell fibers. The investigation involves laboratory experiments and numerical simulations to analyse the impact of various parameters on the paper's characteristics. READ MORE

3. 2. Novel materials from lignocellulosic sources- can they replace thermoplastics?

   University essay from KTH/Fiber- och polymerteknologi

   Author : Emmy Albinsson; Helina Tafesse Belachew; Jasmin Swaich; Hannah Juhlin; [2021]
   Keywords : Emulisonspolymerisation; Biobaserade plaster; Hållbarhet; Polymerer; Bearbetad halm; Kompositer; PISA-raft;

   Abstract : Plastic waste is a severe environmental problem in today's society which has been noticed and discussed during the last couple of years. A constant increase of production over the last decades hasled to a large amount of plastic waste ending up in oceans as microplastics. READ MORE

4. 3. Extensional Instability in Complex Fluids: A Computational Study

   University essay from KTH/Strömningsmekanik och Teknisk Akustik

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

   Abstract : 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. READ MORE

5. 4. Influence of hydrogen on mechanical properties, microstructure and fracture surface of stainless steel 316L and stainless steel 304

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Mustafa Adnan Tawfeeq Salman; [2020]
   Keywords : Hydrogen embrittlement; stainless steel; microstructure; hydrogen charging; slow and fast strain rate.; Väteförsprödning; rostfritt stål; mikrostruktur; väte laddning; långsam och snabb töjnings hastighet;

   Abstract : Since hydrogen is an alternative energy source and has both economic and environmental benefits, it has received more attention. To use hydrogen a certain condition must be met, safe pressurized containers which are often made of metal. The metal isrequired due to the high mechanical strength and reasonable cost. READ MORE

6. 5. Mechanical properties of films made of faba bean protein nanofiber and non-fibrillated protein

   University essay from SLU/Department of Molecular Sciences

   Author : Alice Dunge; [2019]
   Keywords : Faba bean; amyloid; fibrils; meat substitutes; elasticity; stiffness; proteins;

   Abstract : The production of livestock puts a huge strain on our ecosystem and the planet. It is the largest source of greenhouse gases and it causes loss in biodi-versity and pollution of water. One way to reduce these environmental dam-ages is to decrease the intake of meat and increase the intake of plant-based proteins. READ MORE
