  1. 1. Jet fragmentation in shaped charges

    University essay from KTH/Matematik (Avd.)

    Author : Joakim Ericson; [2022]
    Keywords : Shaped charges; numerical simulation; jet fragmentation; Riktad sprängverkan; numerisk simulering; strål-fragmentering;

    Abstract : This master thesis treats the numerical simulation of shaped charge jets and its fragmentation process. Shaped charges is a method to concentrate the effect of an explosive charge and penetrate deeply into a target due to a the formation of a jet with great penetration capabilities. READ MORE

  3. 2. 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

  5. 4. Short-term deformations in clay under a formwork during the construction of a bridge : A design study

    University essay from KTH/Jord- och bergmekanik

    Author : Alexander Berglin; [2017]
    Keywords : Plaxis; Short-term deformations; Elasticity modulus; Correlations; Small-strain stiffness; Korttidssättningar; Elasticitetsmodulen; Korrelationer;

    Abstract : During the casting of a concrete bridge deck, the temporary formwork is causing the underlying ground to deform if a shallow foundation solution is used. There are often demands on the maximum deformation of the superstructure when designing the foundation for the formwork. READ MORE
