METHOD OF DETERMINING STRENGTH OF JOINTS BETWEEN PARTS OF COMPOSITE MATERIALS Russian patent published in 2005 - IPC

FIELD: investigating or analyzing materials.

SUBSTANCE: method comprises exciting and receiving pulses of ultrasonic oscillations in the structure to be tested , measuring parameters of ultrasonic oscillations reflected from the interface between the parts of the integral structure, and determining the strength of part joints from the parameters. The spectrum of the bottom pulse in the shell is measured before and after assembling the integral structure at the same sites. The spectrum of the pulse reflected from the interface between the parts of the integral structure is measured, and the strength of the part joints is determined from the correlation relationship.

EFFECT: enhanced accuracy of measuring.
