The numerical tests have been carried out for rectangular plates with internal defect in a form of a circular hole. The wide variety of hole's positions and diameters were checked. Two identification procedures are presented. Neural network analysis of the calculated eigenfrequencies is the first way to obtain the hole's center coordinates and hole's diameter. The second one is based on analysis of...
This paper presents some examples of updating of computational models of engineering structures. As a tool for model updating artificial neural networks are used. The updated models are verified by the comparison of dynamic parameters of modeled structures obtained from numerical simulations and experimental measurements done on laboratory. The developed updating method is used also in identification...
The backpropagation neural network (NN) was applied to the calculations of response spectrum of traffic induced vibrations in [3, 4, 5 ]. NN was elaborated and fuzzy relations were used this time as shown in Fig. 1. The process mentioned above was done in several phases. As a result a new NN consisted of five layers (40-22-5-37-100 - neurons each) has been built and applied here. The effects of the...
