Bending-induced local buckling during offshore installation of multi-layered FRP pipelines
Pavlou, Dimitrios; Adasooriya, Mudiyan Nirosha Damayanthi (Peer reviewed; Journal article, 2021)In the last two decades FRP pipelines have attracted the attention of the oil industry because of their high strength, excellent fatigue performance and low specific weight. On the other hand, the final cost of installation ... -
Corrosion propagation phase and bond strength degradation of reinforced concrete structures: state of the art
Adasooriya, Mudiyan Nirosha Damayanthi; Samarakoon, Mudiyansele Samindi Manjula K; Gudmestad, Ove Tobias (Journal article; Peer reviewed, 2018)Corrosion causes damage to reinforcing steel in concrete structures and governs the service life of the structures. Currently, researchers are paying attention to modelling the behaviour of the bond between the concrete ... -
Effect of hydrogen on mechanical properties and fracture of martensitic carbon steel under quenched and tempered conditions
Adasooriya, Mudiyan Nirosha Damayanthi; Tucho, Wakshum Mekonnen; Holm, Erlend; Årthun, Terje; Hansen, Vidar; Solheim, Karl Gunnar; Hemmingsen, Tor (Peer reviewed; Journal article, 2020)The change in the mechanical properties of tempered high strength carbon steel (AISI 4130) due to hydrogen embrittlement (HE) has been investigated using slow strain rate tensile tests (SSRT). The heat treatment processes ... -
Environment-assisted fatigue of steel bridges: A conceptual framework for life assessment
Sandviknes, Julie Sofie Stav; Adasooriya, Mudiyan Nirosha Damayanthi; Pavlou, Dimitrios; Hemmingsen, Tor (Peer reviewed; Journal article, 2021)This paper presents a framework based on a recently proposed fatigue strength curve of corroded steel to assess the life of an existing steel bridge exposed to environment-assisted fatigue. Environment-assisted cracking ... -
Fatigue Strength Curve for Tubular Joints of Offshore Structures under Dynamic Loading
Siriwardane, Sudath C.; Adasooriya, Mudiyan Nirosha Damayanthi; Pavlou, Dimitrios (Journal article, 2021)Abstract Offshore structures are subjected to dynamic environmental loads (wave and wind loads). A stress-life fatigue strength curve is proposed for tubular joints which are in the splash zone area of offshore jacket ... -
Fatigue strength degradation of corroded structural details: A formula for S‐N curve
Adasooriya, Mudiyan Nirosha Damayanthi; Pavlou, Dimitrios; Hemmingsen, Tor (Peer reviewed; Journal article, 2019)A formula is proposed to predict fatigue strength of corroded members and joints of steel structures. The concept of the formula is first studied from recently identified mechanism of corrosion fatigue. Hence, the corresponding ... -
Fatigue strength degradation of metals in corrosive environments
Adasooriya, Mudiyan Nirosha Damayanthi; Hemmingsen, Tor; Pavlou, Dimitrios (Journal article; Peer reviewed, 2017)Structures exposed to aggressive environmental conditions are often subjected to time-dependent loss of coating and loss of material due to corrosion; this causes reduction in the cross-sectional properties of the members, ... -
S-N curve for riveted details in corrosive environment and its application to a bridge
Adasooriya, Mudiyan Nirosha Damayanthi; Hemmingsen, Tor; Pavlou, Dimitrios (Peer reviewed; Journal article, 2020-01)A formula for stress‐life curve is proposed to predict the fatigue life of riveted bridges located in corrosive environments. The corrosive environment‐dependent parameters of the S‐N curve are determined based on the ...
