1. Development and evaluation of concepts for a high acceleration test rig : Development of a test rig, which aims to expose components to large and controllable accelerations
Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)Sammanfattning : This thesis work is dedicated towards finding a feasible test rig design, which can expose small components, produced by SAAB, to a variety of accelerations under different conditions. A literature study is conducted with the objective of gathering information regarding high acceleration testing, where relevant components, designs and calculation methods are presented. LÄS MER
2. Exterior ballistics analysis for rocket propelled KE-penetrator - A conceptual simulation study within fluid mechanics and flight mechanics
Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikSammanfattning : This study has investigated the conceptual feasibility of a rocket propelled kinetic energy penetrator (KEP), designed for the handheld recoilless rifle Carl-Gustaf® 84 mm calibre system, from an exterior ballistics perspective. The methodology is based upon evaluating the aerodynamic properties of different conceptual design proposals through CFD-simulations and then performing trajectory analysis to assess their exterior ballistic performance.

3. Simulations of experimental crack development in ceramic material with notched specimen
Master-uppsats, KTH/HållfasthetsläraSammanfattning : Low-density armour often uses ceramic materials, as their high compressive strength and relatively low weight make the material ideal for moving in the field. The ballistic protection works by redirecting the plastic flow of the projectile radially, which reduces penetration. LÄS MER
4. Lättgaskanonens innerballistik : Teori, simulering och parameterstudie
Master-uppsats, KTH/Maskinkonstruktion (Avd.)Sammanfattning : En lättgaskanon är en typ av kanon som används vid experiment där mycket snabba förlopp är av intresse, till exempel hypersonisk strömning och höghastighetskollisioner. Kanontypen når betydligt högre hastigheter än en konventionell kanon då projektilen accelereras genom eldröret av en gas med låg molekylmassa som vätgas eller helium istället för krutgaser. LÄS MER
5. Model for risk evaluation for fragment debris after a grenade detonation
Uppsats för yrkesexamina på avancerad nivå, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : Accidents when using or storing explosives can lead to a large number of casualties and injuries. Hence, it is of vital importance, in all countries, to know the risk and act responsibly when working with explosives. LÄS MER
