Description

Nondestructive testing in civil engineering (NDT-CE) comprises the application of ultrasonic and electromagnetic wave propagation and inverse scattering. The aims of our current research are threefold: (1) Numerical modeling of ultrasonic wave propagation and scattering in concrete with the EFIT code (EFIT: Elastodynamic Finite Integration Technique) to get a better understanding of the ultrasonic wave phenomena in concrete, (2) application of the elastodynamic vector imaging scheme EL-FT-SAFT to modeled data (EL-FT-SAFT: Elastodynamic Fourier Transform Synthetic Aperture Focusing Technique) to detect delaminations in a metal duct or for thickness determination, (3) application of the electromagnetic vector imaging algorithm HD-POFFIS to measurements in order to locate a metal duct in reinforced concrete (HD-POFFIS: Hertzian Dipole Physical Optics Far-Field Inverse Scattering).
