1. 1. Tomography-based Micromechanical Analysis of Novel Composite Material

   University essay from KTH/Hållfasthetslära

   Author : Mattias Grankvist; [2023]
   Keywords : paper mechanics; micro mechanics; numerical analysis; tomography; foam forming; density profile; pappersmekanik; mikromekanik; numerisk analys; tomografi; skumformning; densitetsprofil;

   Abstract : This study explores the performance of porous Paptic paper materials composed of a mixture of softwood and lyocell fibers. The investigation involves laboratory experiments and numerical simulations to analyse the impact of various parameters on the paper's characteristics. READ MORE

3. 2. Micromechanical study of PFZ in aluminum alloys

   University essay from KTH/Hållfasthetslära (Inst.)

   Author : Hossein Shariati; [2016]
   Keywords : precipitate-free zones; strain gradient plasticity; mikromekanik;

   Abstract : There are a number of experiments showing that the ductility of aluminum alloys decreases during age-hardening heat treatment. Observing the grains of age-hardened aluminum alloys at the micron scale, one can notice that there are precipitate-free zones (PFZs) along the grain boundaries. READ MORE

4. 3. Micropumps for extreme pressures

   University essay from Mikrostrukturteknik

   Author : Stefan Svensson; [2009]
   Keywords : Micropump; Micromechanics; Paraffin; Actuator; High-pressure pumping; Steel membrane; Mikropump; Mikromekanik; Paraffin; Aktuator; Höga tryck; Stålmembran;

   Abstract : The objective of this thesis was to improve a paraffin actuated micropump design, to be able to pump against extreme pressures (above 100 bar). This was accomplished by initially studying the membrane activation, using video capturing. READ MORE
