Integration of Non-Destructive Evaluation Based Ultrasonic Simulation

2013-2016

Many of the infrastructure assets today are ageing and require increased care through monitoring. Aeronautical structures are one of the most sophisticated in terms of design since they allow for damage to exist as long as this damage does not become critical. To avoid damage criticality loads monitoring, fatigue life evaluation and defined inspection are key elements of consideration. New coating and printing technologies in materials science, micro-electromechanical systems, enhanced computation power, lower sensing cost and much more has allowed Non-Destructive Evaluation (NDE) to become an integral part of structural components leading towards Structural Health Monitoring (SHM) systems, that will automate a structure's inspection process without compromising safety and reliability.

The project aims to establish a simulation platform for the design of optimized SHM-systems in terms of SHM verification and validation.
