Propagation Characteristics of Ultrasonic Waves in Concrete Medium with Local Damage

Abstract:

Article Preview

The theory of ultrasonic wave propagation characteristic in damaged concrete media was studied in this paper. Basing on the fundamentals of classical elastic dynamics and the model of damaged mechanics,the basic equations of elastic wave propagation in damaged media are established and the example analysis and a numerical calculation are displayed. The basic solutions of the equations is deducted. Because the damage exists in the construction, the concrete’s wave response comprised of the shape,the amplitude and the propagated time of the ultrasonic waves in the structure will change obviously. The transformation mentioned above is provided for further study of inverse analysis and nondestructive test of the structure.
