Dynamisk trykkapasitet i treverk og årringsbreddens betydning for materialegenskapene
Melandsø, Martin (Master thesis, 2022)Denne studien ser nærmere på trykkapsitet parallelt med fiberretningen i treverk under dynamiske tøyningshastigheter, samt årringsbreddens betydning for materialegenskaper som elastitetsmodul og trykkapasitet. Tidligere ... -
Eksperimentelt og numerisk studium av glassfiberarmert polyamid (PA)
Fjermedal, Ole Sverre (Master thesis, 2015)Polyamid (PA) og glassfiberarmert polyamid med fiberandel på 15 vekt% (PA15) og 30 vekt% (PA30) produsert ved sprøytestøping har blitt studert. Det ble utført én-akset strekktester av materialene på prøvestykker med ... -
Enhanced Measurements of Large Deformations of Thermoplastics
Winjum, Olve (Master thesis, 2014)The purpose of this study is to evaluate a numerical material model for thermoplastics developed at SIMLab, NTNU. Several experimental tests, using both HDPE and PVC, were conducted in order to have a basis for calibrating ... -
An experimental and numerical study of bolt and nut assemblies under tension loading
Waldeland, Espen; Johansen, Stian (Master thesis, 2016)The purpose of this master thesis is to investigate how the nut position affects the failure mode of single tensile loaded bolts under quasi-static conditions. A ductile bolt fracture is preferable from an engineering ... -
Experimental and numerical study of dilation in mineral filled PVC
Olufsen, Sindre Nordmark (Doctoral theses at NTNU;2020:388, Doctoral thesis, 2020)This thesis addresses the link between applied load and dilation caused by void growth in mineral-filled PVC employing both experimental and numerical techniques. The influence of stress triaxiality and strain rate on the ... -
