We offer a 4-year PhD position in non-destructive testing (NDT) of composites using the Ultrasonic Polar Scan (UPS) method. The Ultrasonic Polar Scan has been developed in our research group, and is a sophisticated inspection method which provides a unique fingerprint of stiffness and/or damage parameters. The power of this method has been explicitly demonstrated on both metals and composites, yielding the full orthotropic stiffness tensor (2x9 stiffness parameters) from a single measurement. Apart from this, we also found that the UPS fingerprint is sensitive to damage features in composite materials, e.g. delamination, fiber distortion, etc.
This 4-year PhD project involves both experimental and numerical research on the UPS method for the investigation of pre-stressed composites. By performing the UPS inspection during various mechanical loadings of the specimen, access is provided to nonlinear stiffness parameters as well as to damage parameters. This information is of crucial importance for a better understanding of the complex mechanical behavior of composites. This research is in collaboration with KULeuven-KULAK, and you will collaborate with several other PhD students and postdoctoral researchers.
