1. 6. Stochastic Settlement Model Including Creep Effects : Simulation of Groundwater Induced Subsidence

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Pierre Wikby; Ragnar Andersson; [2020]
   Keywords : creep settlement; secondary compression; geotechnical uncertainty; EMBANKCO; groundwater drawdown; time-dependent settlement model; krypsättningar; Sekundärkompression; geoteknisk osäkerhet; EMBANKCO; grundvattensänkning; tidsberoende sättningsmodell;

   Abstract : When underground openings are constructed, groundwater inflow can occur, which might lead to ground settlements, namely in clay. In these types of construction projects, it is beneficial to be able to quantify risks related to these settlements. A framework developed by Sundell et al. (2019, Risk Analysis, Vol. READ MORE

3. 7. Vägsaltets påverkan på närliggande vegetation, mark samt närliggande slitlager

   University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

   Author : Jakob Frängsmyr; Stina Nilsson; [2020]
   Keywords : vägsalt; struktur; halkbekämpning; jord; lignoser; påverkan;

   Abstract : Syftet med detta arbete är att göra en litteraturstudie och sammanställa fakta om hur vägsalt (NaCl, natriumklorid) påverkar vår stadsmiljö samt att få en överblick hur vegetation, slitlager och markytor i närheten av saltbehandlade vägar påverkas av den höga saltningsintensiteten. I arbetet ingår också en kartläggning av vilka andra alternativ och metoder till salt som provats för att eventuellt kunna vara likvärdiga eller bättre i sin funktion och inte vara lika skadliga som salt är för miljön.

4. 8. Compaction Simulation for Prepreg-AutoclaveManufacturing : Improvements and Simplifications of Two Compaction Simulation Methodologies

   University essay from KTH/Lättkonstruktioner

   Author : Charlotte Chan; [2019]
   Keywords : ;

   Abstract : In a competitive market such as the aerospace industry, the use of manufacturing process simulation is vital to decrease time and cost of tooling and process development. In the autoclave process, to obtain an uniform part with no void, it is crucial to understand the compaction phenomenon. READ MORE

5. 9. Friction and wear study of lean powder metallurgy steel in a lubricated sliding contact

   University essay from Uppsala universitet/Tillämpad materialvetenskap

   Author : Caroline Lejonklo; [2019]
   Keywords : Lean steel; Powder metallurgy PM ; Powder metallurgy steel PM steel ; Friction; Wear; Sliding contact; Lubricated; Porosity; Tribology; Adhesive wear; Abrasive wear; Gear; Gear tooth; Particles; Polyalphaolefin 8 PAO 8 ; Contact pressure; Density; Light optical microscopy LOM ; Scanning electron microscopy SEM ; Energy-dispersive X-ray spectroscopy EDS ; Vertical svanning interferometry VSI ; Pin on disc; Pin-on-disc;

   Abstract : A fairly new technology used to produce metallic components is powder metallurgy (PM). Among the advantages with this technique are decreased cost of production for complex-shaped parts, new alloys are made possible, reduced end processing, less material loss, and vibrational damping effects.

6. 10. Evaluation of long-term performance of sodium silicate grouted in embankment dams

   University essay from KTH/Jord- och bergmekanik

   Author : Jenny Fu; [2019]
   Keywords : Sodium silicate; water glass; embankment dams; remedial grouting; dam monitoring;

   Abstract : Embankment dams is the most common type of dams in operation inSweden today. Due to the nature of embankment dams, seepage throughthem will always occur. If the seepage velocity exceeds a critical velocity,internal erosion is initiated, which could lead to damage in form of pipingand sinkholes. READ MORE
