N2 - The CIVA software platform is developed at CEA-LIST and partners in the aim of simulating non-destructive evaluation. Most of the developed models are based on semi-analytical methods since they aren’t heavy on computation time. The ultrasonic simulation tools in CIVA allow to fully predict a real ultrasonic inspection in a various range of applications which requires the computation of the beam propagated, as well as its interaction with flaws. The purpose of this communication is to describe the methods used to model the beam to flaw interaction. Three kinds of models for the scattering of ultrasound by flaws have been integrated in CIVA: approached analytical solutions, exact analytical solutions and numerical modelling methods. Numerous experimental validations of all the developed models are provided including comparisons between different simulation methods. Perspectives of new developments are finally emphasized.
