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 …

Full Matrix Capture & Total Focusing Method

Kevin Chan Examples 0 Comments

The advantage of using a time domain code allows real world experiments to be simulated like for like. Coupled with our highly efficient mechanical solvers allows Full Matrix Capture (FMC) to be carried out in simulation which then can be post-processed using the Total Focusing Method (TFM) to generate the resultant fully focused inspection images. PZFlex offers a wide range …

Composite Fibre Reinforced Plastic Structures

Carbon Fibre Reinforced Plastics (CFRP) and other high strength composite materials offer designers a wide range of performance benefits. However, a major barrier to the use such materials is the cost and complexity of inspection. PZFlex is capable of simulating ultrasonic wave propagation through complex CFRP laminates, allowing new inspections to be developed more rapidly. The complex CFRP weave is …

Summary of the Aluminium Honeycomb Simulation The video shows a pressure load applied to the top Carbon Fibre Reinforced Polymer (CFRP) skin layer on a curved aluminium honeycomb structure. The plot of velocity magnitude (z-component) allows us to visualize the propagation of the wave through a non-defective component. The microstructure of composite structures significantly increases the complexity of simulating wave …

Summary of the PZFlex TOFD Simulation This example shows a typical Time of Flight Diffraction (TOFD) inspection of an anisotropic weld. TOFD is a flexible technique, which relies on a range of mode converted signals to be effective. PZFlex combines the capability of accurately simulating mode conversion in arbitrary geometries, with the speed to run large batches of TOFD models, …
