Damage Detection of Axially Loaded Beam: A Frequency-Based Method
The present study utilizes an analytical method to formulate the three lowest modal frequencies of axially-loaded notched beam through both crack location and load level in a specific format that can be used in existing frequency-based crack-identification methods. The proposed formula provides a basis to shift into two states, one with axial loading and the other without any loading whatsoever...
متن کاملDamage 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...
متن کاملCrack Detection of Fixed-Simply Supported Euler Bernoulli Beam Using Elman Networks
In this paper, the crack detection and depth ratio estimation method are presented in beamlikestructures using Elman Networks. For this purpose, by using the frequencies of modes asinput, crack depth ratio of each element was detected as output. Performance of the proposedmethod was evaluated by using three numerical scenarios of crack for fixed-simply supportedbeam consisting of a single crack...

متن کاملDamage Detection of Beam Structure Using Frequency Response Functions
The global dynamic behavior of structure can affect by the Presence of damage. Hence detection and quantification of damage has a greater significance in the context of structural health monitoring. This paper is based on frequency response function for detecting the presence and severity of damage in the structure. The variations in frequency response function is taken as a feature to detect d...
