Residual stresses and dimensional deviation in metal additive manufacturing: prediction and mitigation methods
(Doctoral theses at NTNU;2020:411, Doctoral thesis, 2020)Additive manufacturing (AM) has attracted wide attention over the past years due to its various advantages, such as design freedom, less production cost, and short production cycles. However, residual stresses and dimensional ... -
Resistance Analysis of Spherical Metal Thin Films Combining Van Der Pauw and Electromechanical Nanoindentation Methods
(Journal article; Peer reviewed, 2018)Although micron-sized metal-coated polymer particles are an important conductive filler material in anisotropic conductive adhesives, the resistance of the particles in adhesive is not well understood. In this study, a van ... -
Resistance measurements of high resistance concrete
(Master thesis, 2015)The importance of concrete resistivity in durability and service life aspects is widely recognized. Within this project, different measurement approaches were evaluated, with associated limitations and advantages. The ... -
Respons i en etterspent skjærvegg fra jordskjelvlaster
(Master thesis, 2013)Det ble tatt utgangspunkt i en oppspent veggskive med slakkarmering. Oppgaven gikk ut på å studere hvordan den oppspente armeringen og slakkarmeringen samvirker, når veggskiven utsettes for seismiske påkjenninger.Spennarmeringen ... -
A Response Spectrum Analysis of Wind Deflection in Railway Overhead Contact Lines Using Pseudo-Excitation Method
(Peer reviewed; Journal article, 2021)The wind deflection of overhead contact lines (OCLs) challenges the stable and safe operation of electrified railways. The steady wind causes the static deflection of the contact line, while the fluctuating wind leads to ... -
Revealing the critical pore size for hydrogen storage via simultaneous enclathration and physisorption in activated carbon
(Peer reviewed; Journal article, 2024)Hydrogen hydrate is regarded as an ideal hydrogen storage medium, but it faces unsolved challenges related to its extreme formation and stabilization conditions. Recent experiments have demonstrated that utilizing porous ... -
