The present disclosure provides methods and systems for performing ultrasonic testing. Reflected acoustic waves are obtained at a detector, the reflected acoustic waves produced by at least one insonification of a component to be tested. The reflected acoustic waves are processed to produce a representation of the component. A location of the component to be tested within the representation of the component is determined. A portion of the representation associated with the component is analyzed to detect a presence of a defect in the component to be tested. An alert indicative of the defect in the component is issued responsive to detecting the presence of the defect.

Ultrasonic testing for defect detection

There are described a system and method for performing ultrasound testing of a component comprising a first material layer and a second material layer bonded by an adhesive layer. The method comprises applying input ultrasound to the component to cause longitudinal propagation of ultrasonic guided waves through the first material layer and the adhesive layer; acquiring acoustic waves from the component, wherein the acoustic waves produced by the longitudinal propagation of the ultrasonic guided waves; generating a signal representation of the acoustic waves; comparing the signal representation of the acoustic waves to a plurality of reference signals to identify a characteristic of the adhesive layer; and outputting an output signal indicative of the characteristic of the adhesive layer.

A ground anchor for anchoring a structure positioned on the ground. The ground anchor comprises a base member, a movable anchoring member and a holding member. The base member is fitted in a hole within the ground and fixedly secured to the ground against removal thereof. The movable anchoring member is mounted to the base member and is movable between a non-anchoring position and an anchoring position. The holding member is mountable to the movable anchoring member when in the anchoring position and to the structure positioned on the ground. When the base member is fixedly secured to the ground, and the movable anchoring member is in the anchoring position with the holding member mounted thereto and to the structure, the ground anchor anchors the structure to the ground. A kit comprising a plurality of such ground anchors is also disclosed.
