  1. 1. Modeling the penetration of fragmented shaped charge jets

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Materialfysik

    Författare :Alexander Palfelt; [2023]
    Nyckelord :Shaped charge; Analytical penetration model; Visualization; Riktad sprängverkan; RSV; Analytisk penetrationsmodell; Visualisering;

    Sammanfattning : The penetration power of a shaped charge is an important characteristic in determining its capability. A model has previously been developed by FOI to analytically predict the penetration of a shaped charge jet striking a target at varying stand-off distances. LÄS MER

  3. 2. Jet fragmentation in shaped charges

    Master-uppsats, KTH/Matematik (Avd.)

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

    Sammanfattning : 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. LÄS MER

  4. 3. How to Achieve Profitable Growht for SME:s : A Study of the Swedish Wood Industry

    Master-uppsats, Linköpings universitet/Institutionen för ekonomisk och industriell utveckling

    Författare :Pontus Larsson; Fredrik Möller; [2020]
    Nyckelord :Tillväxt; SME; aktiviteter;

    Sammanfattning : Profit and growth are the pillars of all business enterprises. The Swedish wood industry has historically been characterized by pressured margins and marginal growth, and in particular SME's have had many challenges in regard to long-term success. LÄS MER

  5. 4. Evaluation of Real Time Grouting Control Theory Using a Varying Aperture Long Slot- VALS

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :Elizaveta Pronina; [2018]
    Nyckelord :Grouting; Real Time Grouting Control theory-RTGC; Penetration Length; Cement-Based Grout; Varying Aperture Long Slot – VALS; hydraulic aperture;

    Sammanfattning : The main goal of the grouting is to seal the fractures in the rock mass,improve the strength properties of the rock mass and decrease deformability. However,the overuse of the grouting should be avoided due mainly to economic reasons,optimizing the project time and sometimes severe environmental issues. LÄS MER

  7. 5. Finite element modeling of straightening of thin-walled seamless tubes of austenitic stainless steel

    Kandidat-uppsats, Högskolan Dalarna/Materialteknik

    Författare :Robert Johansson; [2016]
    Nyckelord :finite element method; FEM; FEA; straightening of tube; arc height; ovalization; roller angle; plastic strain.;

    Sammanfattning : During this thesis work a coupled thermo-mechanical finite element model (FEM) was builtto simulate hot rolling in the blooming mill at Sandvik Materials Technology (SMT) inSandviken. The blooming mill is the first in a long line of processes that continuously or ingotcast ingots are subjected to before becoming finished products. LÄS MER
