In the paper we concentrate on one aspect of the experimental design: how the information coming from an experiment can be utilised for identification of a specific mathematical model. To express the consistency of the data and the model we need some quality measure, allowing to transform our intuition to numbers. As the mathematical tool we propose a version of the statistical procedure of cro...

Crack detection on bridges is an important part of assessing whether a bridge safe for service. The methods using manual inspection and bridge-inspection vehicles have disadvantages, such as low efficiency affecting road traffic. We conducted in-depth study bridge-crack proposed crack identification algorithm Unet, called the CBAM-Unet algorithm. CBAM (Convolutional Block Attention Module) ligh...

Civil infrastructure can suffer from concrete cracks due to the creep, shrinkage, diverse natural loading, aging, and corrosion of reinforcement. Concrete cracks are one of the important features when analyzing the current condition of concrete structures. The shape, length, and width information on concrete cracks are possible to conduct an initial maintenance for the structure safety. General...

The crack breathing model and identification method for rotors using nonlinearity induced by cracks are studied in this work. Firstly, the finite element is utilized to a rotor–bearing system with response-dependent obtain numerical data identification. During modelling, an improved proposed, focused on unreasonable assumption about closure line original position (CCLP) model. Compared model, c...
