A comparative study is performed on the monitoring of delamination healing in CFRP-
ionomer sandwich composites by non-destructive techniques and destructive compression …

A novel approach is presented for the ultrasonic determination of the elastic constants in
plate-like structures of an orthotropic material (eg composites) using a Time-of-Flight version …

In the early 1980's, the ultrasonic polar scan (UPS) technique was developed to assess the
fiber direction of composites in a nondestructive way. In spite of the recognition by several …

Conventionally, the ultrasonic polar scan (UPS) records the amplitude or time-of-flight in
transmission using short ultrasonic pulses for a wide range of incidence angles, resulting in …

Numerical finite-element (FE) simulations and postprocessing analysis methods are
presented for ultrasonic polar scan (UPS) measurements involving a circular phased array …

In the context of designing a next-generation ultrasonic polar scan (UPS) measurement
system for viscoelastic material characterization, a novel approach is proposed, which draws …

The ultrasonic polar scan (UPS) technique was developed in the 1980's as a means to
nondestructively determine the fiber direction of composites. Although recognized by many …

The motivation for this effort is the desire of the United States Air Force (USAF) to implement
slow crack growth damage tolerance lifing (DTL) for its polymer matrix composite (PMC) …

Previous electromagnetic (EM) wave‐based approaches to evaluate material physical
properties are focused on applications of GHz and THz. High‐frequency radio‐frequency …

Currently, exciting new materials such as fibre reinforced plastics (FRP) are being
developed for the inclusion in load bearing components of modern industries. In order to …
