  1. 1. Plastic deformation of hot riveted joints acting in shear

    University essay from KTH/Bro- och stålbyggnad

    Author : Victor Gard; [2023]
    Keywords : ;

    Abstract : A popular way to maintain old rivet connections is to reuse the old connection and replace the old rivets with high grade steel bolts. In doing so the behavior of the joint can change due to the new geometry, where a gap between the new bolt and the rivet hole emerges. READ MORE

  3. 2. Development of Elastic Mechanism for actuation of Valve

    University essay from KTH/Maskinkonstruktion

    Author : Nidhi Menon; [2023]
    Keywords : Compliant mechanism; Engine; HGR valve; Heat gas recirculation; Eftergivlig mekanism; HGR-ventil; läckage; varmgasåtercirkulationsventilen;

    Abstract : The HGR valve, or hot gas recirculation valve, is an essential component of modern internal combustion engines. Its main function is to reduce emissions of nitrous oxide (NOx), which is a harmful pollutant produced during combustion. READ MORE

  4. 3. Analysis of hot workability in 316L steel using ductile fracture criterions

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Viktor Strid; [2022]
    Keywords : Ductile fracture criterion; Finite Element Method; Hot working; 316L Stainless Steel; Fracture Modeling; Gleeble; Hot deformation;

    Abstract : The focus of this thesis is to develop a simulation model for predicting ductile fractures during hot working at Alleima. The main fracture mechanism in these conditions is ductile fracture by void coalescence. The ductile fractures are caused by the linking of voids that appear when there is large plastic deformation near second-phase particles. READ MORE

  5. 4. Identifying risks of AdBlue spray on stainless steel surfaces

    University essay from KTH/Kemiteknik

    Author : Evelina Tvinne Flyg; [2021]
    Keywords : Urea; Stainless steel; SCR; Deposit; Corrosion; Urea; rostfritt stål; SCR; Avlagring; Korrosion;

    Abstract : Utsläppskontroll, reglerad av allt strängare lagstiftning, ställer höga krav på utvecklingen av noggranna efterbehandlingssystem för avgaser. När det gäller utsläpp från dieselmotorer utgör NOx-minskning en av de största utmaningarna. För tunga fordon tacklas denna utmaning ofta genom ett SCR-system. READ MORE

  6. 5. Temporal and genetical constraints of the Cu-Co Vena-Dampetorp deposit, Bergslagen, Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Dino Leopardi; [2020]
    Keywords : Bergslagen; Vena; Dampetorp; Cu-Co; sulphide melting; Bastnäs-type; cobaltite; arsenopyrite; titanite dating; sulphide mineralization; sulphide re-mobilisation.; Earth and Environmental Sciences;

    Abstract : The Bergslagen Province is known for containing major Zn-Pb-Ag and Zn-Pb-Cu-Ag sulphide mineralizations with associated iron-oxide skarns and a lot of research have focused on understanding them. However, Cu-Co deposits like the Vena-Dampetorp deposit have received less attention. READ MORE
