Abstract EN
In this research, dynamic response of a cracked shaft having transverse crack is analyzed using theoretical neural network and experimental analysis.
Structural damage detection using frequency response functions (FRFs) as input data to the back-propagation neural network (BPNN) has been explored.
For deriving the effect of crack depths and crack locations on FRF, theoretical expressions have been developed using strain energy release rate at the crack section of the shaft for the calculation of the local stiffnesses.
Based on the flexibility, a new stiffness matrix is deduced that is subsequently used to calculate the natural frequencies and mode shapes of the cracked beam using the neural network method.
The results of the numerical analysis and the neural network method are being validated with the result from the experimental method.
The analysis results on a shaft show that the neural network can assess damage conditions with very good accuracy.
