  1. 11. Effect of strain rate on continuum and pre-cracked polymer failure

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Pratik Rajesh Powar; Ashkan Raeisi; [2021]
    Keywords : DIC; LDPE; MCalibration; Polymer; Strain Rate;

    Abstract : The main intention of this thesis work was to investigate the effect of strain rate on continuum and pre-cracked polymer failure. Low-Density Polyethylene (LDPE) was chosen to study experimentally and numerically. In order to cover wide range of strain rates, four specific strain rates were selected for the uniaxial tensile tests. READ MORE

  3. 12. Studying American Football with Finite Element Analysis and Video Analysis

    University essay from KTH/Matematik (Avd.)

    Author : Daniel Sliwinski; [2021]
    Keywords : Medical Engineering; Helmet to Helmet impacts; Helmet to Ground impacts; Finite Element Analysis; Video Analysis; GHBMC; Maximum Principal Strain; American Football; Medicinsk teknik; Hjälm mot hjälm tackling; Hjälm mot mark tackling; Videoanalys; Finite Element analys; GHBMC; Maximum Principal Strain; Amerikansk fotboll;

    Abstract : Head injuries in American football is a serious issue regarding player health which is highly affected by velocity and its direction. Impact location can affect the severity of the head injury in both helmet-to-helmet impacts and helmet-to-ground impacts hence the understanding of concussive outcome from velocities and impact locations must be improved.

  4. 13. Metamorphic microtextures and mineral assemblages in orthogneisses in NW Skåne – how do they correlate with technical properties?

    University essay from Lunds universitet/Geologiska institutionen

    Author : Maria Eleni Taxopoulou; [2020]
    Keywords : granitic gneiss; Eastern Segment; Söderåsen; rock quality; quantitative analyses; grain size; aspect ratio; circularity; mineralogy; Earth and Environmental Sciences;

    Abstract : Glacifluviala avlagringar har varit de vanligaste källorna för byggmaterial i Sverige under de senaste decennierna. De är dock ändliga resurser som måste bevaras eftersom de också fungerar som akvifärer. READ MORE

  5. 14. Analysis of Paperboard Performance using Digital Image Correlation

    University essay from KTH/Hållfasthetslära

    Author : Yiming Liang; [2020]
    Keywords : Paperboard; Digital image correlation; Comparable stages; Compensation; Kartong; Digital bildkorrelation; Jämförbara tillstånd; Kompensation;

    Abstract : The performance of paperboard materials in packaging application has been investigated and evaluated for a long time. This is because it plays a decisive role for product protection and decoration in packaging applications. Potential damages during transportation sometimes affect the consistency of the performance.

  6. 15. Investigating strains on the Oseberg ship using photogrammetry and finite element modeling

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Andreas Eriksson; Erik Thermaenius; [2020]
    Keywords : Oseberg ship; strain; strain analysis; mechano-sorptive strains; Delaunay triangulation; finite element analysis;

    Abstract : The Oseberg ship is known as one of the finest surviving artifacts from the Viking age, with origins dated back to the 800s. The ship has been displayed in the Viking ship museum in Oslo since 1926. The nearly 100 years on museum display along with the over 1000 years it was buried has weakened the structure of the ship.
