Crack Detection by Bispectral Analysis
SOMMARIO La misura di vibrazioni é frequentemente adottata per individuare cricche di fatica nelle strutture. In questo lavoro é presentata una metodologia, basata sull'analisi bispettrale, al fine di rilevare la presenza di una cricca in una trave a sezione costante; la tecnica di analisi del segnale è applicata alla risposta del sistema sottoposto ad eccitazione random mediante shaker. ABSTRA...
متن کاملCrack Detection In Functionally Graded Beams Using Conjugate Gradient Method
In this paper the conjugate gradient (CG) method is employed for identifying the parameters of crack in a functionally graded beam from natural frequency measurement. The crack is modeled as a massless rotational spring with sectional flexibility. By using the Euler-Bernoulli beam theory on two separate beams respectively and applying the compatibility requirements of the crack, the characteris...
متن کاملCRACK DETECTION IN CONCRETE BEAM USING OPTIMIZATION METHOD
Structural damage detection is a field that has attracted a great interest in the scientific community in recent years. Most of these studies use dynamic analysis data of the beams as a diagnostic tool for damage. In this paper, a massless rotational spring was used to represent the cracked sections of beams and the natural frequencies and mode shape were obtained. For calculation of rotational...
متن کاملComputer Vision Based Crack Detection and Analysis
Cracks on a bridge deck should be ideally detected at an early stage in order to prevent further damage. To ensure safety, it is necessary to inspect the quality of concrete decks at regular intervals. Conventional methods usually include manual inspection of concrete surfaces to determine defects. Though very e↵ective, these methods are time-ine cient. This paper presents the use of computer-v...
متن کاملFatigue Crack Detection Using Piezoelectric Elements
Crack detection using piezoelectric sensors have widely been reported in many research papers. In most of these studies, the cracks considered are generally artificially induced and the piezoelectric sensors are not subjected to fatigue loading. This paper presents a set of fatigue tests results demonstrating the effectiveness of piezoelectric elements in crack detection. The results presented ...
