Damage detection based on modal parameter changes has become popular in the last few
decades. Nowadays, there are robust and reliable mathematical relations available to …

Identifying cracks in the incipient state is essential to prevent the failure of engineering
structures. Detection methods relying on the analysis of the changes in modal parameters …

Early detection of cracks in beams, machines, and other structural elements with
applications in the maritime industry, oil and gas sector, mining sector, and other systems or …

Non-destructive testing of structures involving vibration-based damage detection methods
implies knowing the beam's boundary conditions. For perfect boundary conditions …

During functioning time, structures such as beams are subjected to a variety of loads caused
by the working conditions and environment, which can lead to the development of cracks …

Because real beams have non-ideal boundary conditions, it is necessary to use advanced
models to determine the real modal parameters. The model proposes imperfect clamping …

We propose herein a mathematical relation to calculate the severity of transverse cracks
which affect a prismatic beam. It is known that the damage severity depends on the depth of …

We propose in this paper a mathematical relationship to calculate the natural frequency
shifts of beams due to multiple cracks. The relationship is based on the application of the …

The paper presents the investigations made to evaluate a model that predicts the frequency
shifts due to T-shaped cracks. We developed the model basing on the energy loss due to the …
