    摘要： A system and methods are provided for evaluating a bond between structures. The system includes an assembly of at least two bonded structures. The assembly has a front surface, a back surface, a thickness, and a bond disposed between the front surface and the back surface. At least one delay component is attached to the front surface of the assembly having a body having a front face, a back face, and a thickness. The system further includes a laser source capable of depositing laser energy onto a front face of the delay component, where a first portion of the laser energy is absorbed by the front face of the delay component to generate a first compression wave that propagates through the body of the delay component. A second portion of the laser energy is absorbed by the back face of the component to generate a second compression wave that reflects off of the back surface of the assembly to produce a tensile wave that stresses the bond.

    摘要： A bond inspection system may include a material that reacts to applied activation energy by creating a compression wave, the material positioned adjacent a surface of a structure having a bond to be inspected and shaped in a predetermined pattern, such that reaction of the material causes compression waves to travel through the surface and structure; a source of activation energy capable of directing the activation energy at the material; and a controller programmed to actuate the source of activation energy to direct the activation energy at discrete portions of the predetermined pattern of material in a predetermined sequence selected to create a plurality of the compression waves so that the compression waves reflect from an opposite side of the structure as a plurality of tension waves that combine at substantially the same time at a bondline of the structure to be inspected.
