Elastic constants are key parameters to quantitatively evaluate material strength of
anisotropic carbon fiber-reinforced plastic (CFRP) that is increasingly utilized in commercial …

The determination of elastic constants of a transversely isotropic carbon fiber reinforced
plastic (CFRP) composite is the prerequisite of mechanical strength calculation, material …

Already in the early 1980's, it has been conjectured that the pulsed ultrasonic polar scan (P-
UPS) provides a unique fingerprint of the underlying mechanical elasticity tensor at the …

In this paper, the hybrid compliance-stiffness matrix method for simulating wave propagation
in (delaminated) multilayered media with viscoelastic anisotropy has been confronted with …

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 …

In a conventional ultrasonic polar scan (UPS) experiment, the amplitude or time-of-flight-
diffraction (TOFD) values of the transmitted and/or reflected acoustic pulse are recorded for a …

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 …

This study investigates the use of both the amplitude and time-of-flight based pulsed
ultrasonic polar scan (P-UPS) for the nondestructive detection and evaluation of fatigue …

The development of new composite materials, often anisotropic in nature, requires intricate
approaches to characterize these materials and to detect internal defects. The Ultrasonic …

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 …
