Damage Detection in Beam-like Structures using Finite Volume Method

In this paper the damage location in beam like-structure is determined using static and dynamic data obtained using finite volume method. The change of static and dynamic displacement due to damage is used to establish an indicator for determining the damage location. In order to assess the robustness of the proposed method for structural damage detection, three test examples including a static analysis, free vibration analysis and buckling analysis for a simply supported beam having a number of damage scenarios are considered. The acquired results demonstrate that the method can accurately locate the single and multiple structural damages when considering the measurement noise. Finite volume method results provided in this study for finding the damage location is compared with the same indicator derived via finite element method in order to evaluate the efficiency of FVM. The acquired results are showed a good match between both Finite Volume method and Finite Element method and there are reasonable correlations between ones.
