1. 1. A comparative study regarding weakly stationarity assumptions and time dependency : Signal processing of vibrational loading and its influence on fatigue life

   University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

   Author : Rikard Dahlman; Ebba Johansson; [2018]
   Keywords : Stationarity; Test for weakly stationarity; Reverse arrangements test; Runs test; Signal processing; Fatigue life; Time dependency; Piecewise weakly stationary.;

   Abstract : Simplifications regarding calculations of fatigue life due to vibrational loading is based on weakly stationarity assumptions which is a time independent method. The hypothesis was based on the uncertainty of these assumptions. The aim of this study was to examine whether the analysed data fulfilled the assumptions of weakly stationarity. READ MORE

3. 2. Edge effect on abrasive wear mechanisms and wear resistance in WC-6wt.% Co hardmetals

   University essay from Institutionen för ingenjörsvetenskap, fysik och matematik

   Author : Teresa Adeva Rodil; [2006]
   Keywords : Wear reistance on abrasive wear;

   Abstract : Wear of hardmetals is a complicated topic because the wear resistance and the wear mechanisms are influenced by microstructural factors. Although edge wear resistance has a vital importance, most of the researches made in laboratories are related to flat wear resistance using coarse abrasive paper. READ MORE
