  1. 36. Numerical modelling of lime-cementcolumns in the passive zone of excavations in soft clays

    University essay from KTH/Jord- och bergmekanik

    Author : Anaëlle Gilot; [2021]
    Keywords : Deep mixing; lime-cement columns; excavations; clay; finite element method; advanced constitutive model; Mélange profond; colonnes de chaux-ciment; excavations; argile; méthode des éléments finis; modèle constitutif avancé; Jordförstärkning med kalk-cement pelare; utgrävningar; lera; finita elementmetoden; avancerad konstitutiv modell;

    Abstract : Excavations in soft clays come with a number of specific challenges. The use of lime-cement columns in the passive zone of such works represents a promising solution to some of these problems, such as basal heave stability or excessive deformations. READ MORE

  3. 37. Analysis of a Plate of High Strength Steel: Simulation of Impact and Determination of Residual Stresses

    University essay from KTH/Hållfasthetslära

    Author : Martin Hviid; [2021]
    Keywords : ;

    Abstract : In this study a finite element model has been created in ABAQUS/Standard in order to replicate impact tests performed by SSAB and to determine residual stresses in a plate. Uniaxial tensile tests have been done in order to determine the plastic behaviour of a high strength steel from the manufacturer SSAB and to determine whether the material can be assumed to be isotropic.

  4. 38. Simulation of Residual Stresses in Cemented Carbide

    University essay from KTH/Teknisk mekanik

    Author : Emma Lundin; [2021]
    Keywords : ;

    Abstract : Cemented carbides are used in a multitude of applications within machining as they can withstand tough conditions. Therefore, the stress state in a virgin material is of interest. READ MORE

  5. 39. Wear Performance Investigation of Metal Matrix Composite

    University essay from Lunds universitet/Industriell Produktion

    Author : Manideep Beri; Hema Kalidasu; [2021]
    Keywords : Metal Matrix Composites; Hadfield Steel; Tungsten carbide; Technology and Engineering;

    Abstract : To improve the abrasive wear resistant which is governed by a combination of both high hardness and toughness, WC particles were used to reinforce the Hadfield steel. This latter is known with its good work hardening property. WC is mainly considered for its combination of suitable hardness and toughness. READ MORE

  6. 40. Login hardening with Multi-factor Authentication

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Michaela Bergman; [2021]
    Keywords : multi-factor authentication; authentication; security; usability; cost; biometrics; biometric authentication; openid connect; oauth 2.0; PKCE; account recovery; security threats; authentication factors; Technology and Engineering;

    Abstract : The aim with this Master’s Thesis work was to conduct research about different available authenticators, as well as implementing a multi-factor authenticator into the currently used login-application. The research included biometric authentication technologies, and investigation of how to implement these to create a highly secure and customizable multi-factor authentication for My Axis-accounts for Axis Communications in Lund.
