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 …

A new eddy current testing method for non-contact strain monitoring of continuous carbon
fiber-reinforced plastics (CFRPs) was developed. The strain of a CFRP was estimated from a …

A thermal stress measuring method based on the digital shearing speckle pattern
interferometry (DSSPI) is proposed in this paper. The concept of the method is that the …

During tensile testing of materials, strain measurement is conducted using either contact or
non-contact methods. Contact methods offer high accuracy and precision but are limited by …

Ultrasonic polar scan (UPS) records the amplitude in transmission for a wide range of
incidence angles, providing a UPS image with characteristic contours reflecting the acoustic …

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 ultrasonic polar scan (UPS) technique originated in the 1980's as a sophisticated
method for inspecting composites. However, it is only in recent times that the true …

抄録 Stainless alloy is widely used in implants, dams and bridges because of its high
corrosion resistance. However, these structures can be exposed to loads during their useful …
