Damage size identification of thick steel beam based on ultrasonic guided wave

SUN Kai1,MENG Guang1,YE Lin2,LI Fu-cai1 (1.State Key Laboratory of Mechanical System and Vibration,Shanghai Jiaotong University,Shanghai 200240,China; 2.Laboratory of Smart Materials and Structures(LSMS),School of Aerospace,Mechanical and Mechatronic Engineering,The University of Sydney,NSW 2006,Australia )  
The possibility of damage size identification of relatively thick structures with PZT transducers using guided wave approach was discussed.Based on optimized excitation wave parameters and PZT transducers layout,the finite element simulation was carried out with commercial FE analysis software Abaqus.The FE modal was then validated by experiment,and good agreement is found between the results of experimental measurements and numerical simulation.Simulation results show that the arrival time and magnitude of damage-reflected wave packet as well as transmitted wave packet change regularly with the increasing of damage depth or thickness,based on which the features can be extracted for the purpose of damage size judging.
