Description

In order to cope with real-life NDT situations, we have to develop numerical time domain modeling tools which are based on direct numerical methods because only very few idealized canonical NDT situations can be modeled with analytical methods. Well known direct numerical procedures for the time domain modeling of ultrasonic waves (elastodynamic waves) are given in the references [1]–[6]. One of these, the Elastodynamic Finite Integration Technique (EFIT) [6, 7], has been applied to several real-life NDT situations. A subset of six 2D EFIT simulations include the NDT of a welded high pressure vessel, ultrasonic pipeline inspection, NDT of concrete (NDT-CE) (the reader is referred to [8]), NDT of fiber reinforced laminates, NDT of fiber reinforced T-stringer, and transducer modeling.

Ultrasonic Modeling of Real-Life NDT Situations: Applications and Further Developments
