... that it creates integrity concerns on the pipeline. This research aims to study the effects of an ILI tool’s passage through exposed and partially supported pipes under a variety of boundary and loading conditions. A finite element model of an exposed pipe section is developed based on the Timoshenko beam theory...

... and the harvester are discretized using 1D Euler–Bernoulli beam element that has two bounding nodes. Each node has two degrees-of-freedom which are the transverse mechanical displacement and its derivative (rotation). On the other hand, the fluid domain is discretized using quadrilateral four-node finite elements...

... (FDM) or the finite element method (FEM) is widely applied [ 3 ]. Ockendon and Taylor [ 4 ] established an approximate analytical formulation to determine contact force. Vinayagalingam [ 5 ] studied contact force variations and pan-head trajectory by using the FDM. Wormley et al. [ 6 ] obtained free...
