Offer Description
Objectives: To develop a fast and robust framework for combined defect ICQ and structural integrity evaluation in advanced thermoplasticcomposites ultrasonically welded joints, using in situVibro-Thermography analyses(VTA) – a SoA LR NDI technique combining mechanical vibrations with infrared thermography to reveal hidden welding flaws – and a new ML model to translate the welding process parameters and VTA data directly into defect metrics that can be assessed for criticality, to assess any potential welding repair requirements.



The following methodology is defined: i) Fabrication, VTA & XRM NDI, testing of representative lab-scale thermoplastic composite joints (e.g. SLS coupons representative of large-scale aerospace structural joints); ii) Initial ML tool development for defect ICQ and spatial mapping (develop & train a surrogate model on XRM-informed VTA data, for automated defect ICQ and mapping in welded joints); iii) Development & validation of a macro-scale digital shadowing tool for assessing defect criticality (using a SoA macro-scale modelling approach with cohesive surface representation of welded interfaces, implant the VTA-inspected disbond patterns. Validate this approach with experimental coupon data of step i), assessing defect severity and establishing novel single-defect DAC for welded joints); iv) Extend surrogate model to correlate between real-time VTA imaging and defect severity, using the numerical r
