    • Comparison of DOFS attachment methods for time dependent strain sensing 

      Wang, Shaoquan; Sæter, Erik; Lasn, Kaspar (Peer reviewed; Journal article, 2021)
      Structural health monitoring (SHM) is a challenge for many industries. Over the last decade, novel strain monitoring methods using optical fibers have been implemented for SHM in aerospace, energy storage, marine, and civil ...

    • Embedded optical fibres for monitoring pressurization and impact of filament wound cylinders 

      Sæter, Erik; Lasn, Kaspar; Echtermeyer, Andreas; Nony, Fabien (Journal article, 2018)
      Filament wound composite pressure vessels have found use throughout many industries for storing high-pressure gases. The ability to investigate the vessels for possible damage from accidental impact loads is important for ...

    • Predicting multi-axial diffusion of water in laminated composite structural components 

      Fan, Yiming; Krauklis, Andrey, E; Gagani, Abedin; Sæter, Erik; Echtermeyer, Andreas; Muliana, Anastasia H (Journal article, 2021)
      This study examines the diffusion of water in fiber-reinforced polymer (FRP) laminated composites, comprising epoxy resin and unidirectional glass fibers, at different material and structural scales. Experiments on the ...

    • Sensing of Structural Damage with OBR Based Fibre-Optic Networks 

      Lasn, Kaspar; Sæter, Erik; Echtermeyer, Andreas (Chapter, 2018)
      Optical fibre networks based on optical backscatter reflectometry i.e. the OBR technology is a new and promising method for the inspection of safety critical structures. It utilizes regular telecommunications grade optical ...

    • Utmattingslevetiden av limfuger 

      Sæter, Erik (Master thesis, 2016)
      Denne masteroppgaven har undersøkt effekten av utmatting på «single lap»-forbindelser gjennom eksperimentelt arbeid og tøyningsfeltanalyse. Hovedfokus har vært på 100 mm «single lap»-forbindelser bestående av stål og ...

    • Zero Stress Aging of Glass and Carbon Fibers in Water and Oil—Strength Reduction Explained by Dissolution Kinetics 

      Echtermeyer, Andreas; Krauklis, Andrey; Gagani, Abedin; Sæter, Erik (Journal article; Peer reviewed, 2019)
      Understanding the strength degradation of glass and carbon fibers due to exposure to liquids over time is important for structural applications. A model has been developed for glass fibers that links the strength reduction ...
