Evaluation of four-point transient potential drop on conductive plates
Persvik, Øyvind Othar Aunet; Bowler, John R (Journal article; Peer reviewed, 2017)We have derived an analytical solution for the transient potential drop due to a step function excitation of a four-point probe on a conducting plate. Similar expressions have already been developed based on a previous ... -
Modeling and experiments in transient potential drop measurements for non-destructive evaluation
Persvik, Øyvind Othar Aunet (Doctoral theses at NTNU;2022:146, Doctoral thesis, 2022)Electromagnetic non-destructive evaluation methods are commonly used in inspection and health monitoring of steel structures. The electromagnetic properties of ferromagnetic steel are well known for being correlated with ... -
