INTEGRATED SIMULATION AND EVALUATION OF ULTRASONIC INSPECTIONS

Objective

The goal of the project is to develop a methodology and a system which allows simulation of ultrasonic testing inspections especially of complicated geometries. Also the comparison of simulated and measured data will be supported by this system.
With ULIAS, a prototype of a powerful modeling and analysis system is now available. The main goal was to have an integrated system capable of handling complex geometries. This goal has been reached with the prototype system. Two different and powerful modeling methods are available in ULIAS. This together with the wide variety of reconstruction methods (FTET, FT-SAFT, 3D-SAFT, CBA, HOLO) make decisions in critical inspections much easier. Moreover, the UDEF file format can be viewed as basis for a data exchange format among the ULIAS users.
The system will be realized by integration and if necessary modification or further development of the following modules :

-3 D handling of geometry (CAD, Preprocessing, Postprocessing)
-modelling - Scanning path optimization - Imaging methods as central beam approximation, topography, SAFT
-flaw analysis and interpretation.

The project is based on the result of the PISC III modelling group and on existing techniques of the partners and subcontractors. The results of the project will be a helpful tool for :

-Estimation of inspectability of a specimen to be constructed
-planning of inspection strategy, which means transducer design, scanning path optimization and selection of instrumentation
-inspection demonstration by simulation : - analysis and interpretation of insertion data, especially sizing of defects with respect to fracture mechanics
-documentation of NDT results : - assurance of inspection quality.

Comprehensive tests will be carried out by comparison of simulated UT data with measured ones using mock-ups which cover a wide range of applications.
