Design of nature-inspired components with tailored geometry for high mechanical performance
Jørgensen, Morten Mosvold (Master thesis, 2021)The purpose of this thesis is to study the effect of adding tailored geometries in specimens to strengthen them and increase their fatigue resistance. Several studies are performed on different geometries. The specimens ... -
Fatigue of additively manufactured 316L stainless steel: The influence of porosity and surface roughness
Solberg, Klas; Guan, Shuai; Javad Razavi, Seyed Mohammad; Welo, Torgeir; Chan, Kang Cheung; Berto, Filippo (Journal article; Peer reviewed, 2019)The fatigue behaviour of additively manufactured (AM) 316L stainless steel is investigated with the main emphasis on internal porosity and surface roughness. A transition between two cases of failure are found: failure ... -
Post-tension as a mechanical solution to improve FFF Z-strength: A quantitative research on how post-tension affects static strength and fatigue life for PETG specimens in three-point bending tests
Håøya, Peder August (Master thesis, 2022)Komponenter laget med smeltet filamentfremstilling (fused filament fabrication, FFF) har dårligere mekaniske egenskaper i retningen den er produsert, ofte kalt Z-styrke. Dette skyldes hovedsakelig svakere materialegenskaper ...
