Abstract

In this paper, the ultrasonic transmission process and damage detection in rod structure are experimentally studied. In the finite element simulation, according to the nonlinear interaction between the different Lamb wave excitation signals and the fixed size crack on the rod, the signal mechanism is analyzed and how to locate the damage signal is explained. The fatigue crack evolution of rod assembly is further tested by experimental method. It is consistent with the simulation results. It is found that the ultrasonic guided wave signal with excitation is very sensitive to cracks. Finite element analysis and excitation signals can be used as potential methods for quantitative evaluation of cracks in metal parts. The results of this study provide a basis for modeling and simulation using finite element in the field of nondestructive evaluation and structural health monitoring
