NDE inspection performance depends on many influential parameters.

It is difficult to precisely assess them with experimental trials, as all these parameter combinations would represent thousands of situations.

With simulation, and even moreso with metamodels available in CIVA software, you can reach this multi-dimensional analysis level.

Based on a simple UT inspection example, discover through this video the tools that can help you go one step further in your design, optimization or reliability studies in NDE. See the effects of slight changes in probe position, refracted angle and other parameters on amplitude results. This CIVA example only required 2 hours of computation, on a simple computer!

These metamodel features are included with the purchase of CIVA UT, ET, RT/CT and GWT modules.

Since Structural Health Monitoring (SHM) sensors are embedded in the monitored structure, it is even more important than in traditional NDE to design and qualify them carefully before implementation. Simulation is a must have! CIVA now includes a new module to model SHM by Guided Waves, CIVA SHM.

Based on an innovative technique providing very competitive computation times, CIVA SHM is a must-have tool for SHM engineers. With CIVA SHM, engineers can lower the need for costly and time-consuming mock-ups:

• Design monitoring strategy: Define the relevant number of sensors before preparing prototypes and then embedding sensors in a real structure… For life!
• Demonstrate monitoring performance: Study influential parameters to assess and improve SHM system reliability
• Provide data sets for POD evaluation: Generate massive data at low cost thanks to modelling for Probability of Detection campaigns
• Better understand SHM signals: Simulate different scenarios to better identify defect signals from other features and geometrical effects

In an easy-to-use dedicated user interface, you can represent the specimen to be monitored, the network of sensors and the target defects, then CIVA SHM computes the sensor responses. Dispersion curves are also provided.

CIVA SHM can simulate metallic or composite stratified planar components with potential curvatures or stiffener as well as metallic pipe configurations.

More information available in this document and on the CIVA SHM dedicated page.
