Abstract: This paper utilized finite difference schemes to simulate the propagation of acoustic emission (AE) waves in isotropic, anisotropic plates as well as perfect-bonded bimaterial composite plates. ...

Abstract: This paper studies the absolute calibration of acoustic emission signals. The experiments were conducted on a thin plate. Fracture of a glass capillary was adopted to generate a vertical force ...

Abstract: A modified theory of acoustoelasticity is proposed to include the effect of small plastic deformation on propagational speeds of elastic waves in orthotropic media. In the constitutive equation ...

Abstract: Ultrasonic experiments are preformed on a carbon steel specimen to determine the change of elastic wave speeds by plastic strains and residual stresses in the specimen. Under repeated uniaxial ...
