1. 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
2. Laddbarhet och borrhålsstabilitet i produktionsborrhål - Kiirunavaara gruva
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : Vid laddning av produktionsborrhål i Kiirunavaara gruva (KUJ) uppstår ofta problem med att nå botten av borrhålen, vilket medför att laddbarheten minskar. En låg laddbarhet i produktionsborrhålen leder till en försämrad fragmentering, lossbrytning av malmen och störningar i det efterföljande gravitations- och produktionsflödet. LÄS MER
3. Evaluation of Peridynamics and Its Application in Harmonic-Structured Material Simulations
Master-uppsats, Lunds universitet/MekanikSammanfattning : Materials are constantly sought to be improved in different manners. Two of the most common characteristics to improve are strength, and ductility. Historically, materials are modified homogeneously to achieve improvement, while the past century has also seen composite materials becoming standard-issue within various industries. LÄS MER
4. Influence of hydrogen on mechanical properties, microstructure and fracture surface of stainless steel 316L and stainless steel 304
Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknikSammanfattning : Since hydrogen is an alternative energy source and has both economic and environmental benefits, it has received more attention. To use hydrogen a certain condition must be met, safe pressurized containers which are often made of metal. The metal isrequired due to the high mechanical strength and reasonable cost. LÄS MER
5. Självuttorkning i betong med aluminatrika tillsatsmaterial
Master-uppsats, Lunds universitet/Avdelningen för ByggnadsmaterialSammanfattning : This master thesis work concerns the effect of high-alumina additives on the selfdesication of concrete. The purpose of the work was to examine the possibilities to optimize the binder-content of concrete with regards to self-desiccation. Two highalumina additives have been examined. LÄS MER
