Advanced NDE Simulation Using PZFlex

Kevin Chan Case Studies 0 Comments

Simulation of ultrasonic inspection has been a key tool in the NDE industry for over 40 years, for example ray-tracing models helped engineers safely build and maintain the last generation of nuclear power plants in the 1980’s. Fast, realistic and accurate simulation offers tremendous value in accelerating the adoption of new inspection methods for new components, infrastructure and materials that are used in modern industry. However, as the complexity of modern materials increases with CFRP, and additive manufacturing methods, so does the demands on the inspection techniques, which have to be explored and validated before a new component, or material, can be approved for use.

This is where powerful FEA can help NDE engineers quickly design and test novel inspection modalities in practical situations with realistic materials. By reducing the number of approximations, not only in physics, but in geometry and microstructure, FEA can provide a more complete insight in the performance of ultrasonic techniques, without recourse to expensive test-piece fabrication.

The key to using this capability is having access to a tool that can capture all the coupled effects, and perform computations in an economical manner in terms of computational resource. This presentation discusses the challenges faced in the advanced NDE inspections, and how simulation can help alleviate those challenges.

By using PZFlex as the FEA engine, engineers are able to deliver massive simulations in accelerated timeframes – making FEA a viable tool for these problems, where previously it would have been considered too expensive computationally.
