  • Systems and methods for assessing the quality of adhesive bonds
    Patent number: 10989680
    Abstract: In one embodiment, assessing the quality of an adhesive bond of a composite material includes passing a vector electric field through a thickness of the composite material, measuring dielectric properties of the composite material, determining one or more dielectric parameters of the composite material, and comparing the one or more dielectric parameters with one or more reference dielectric parameters.

  • Dynamic measurement of material strength and life under cyclic loading
    Patent number: 5305645
    Abstract: A conventional dynamic testing machine, such as an MTS (Material Test System) is modified to allow for a new method for dynamically monitoring fatigue damage in a specimen. Load and stroke signals are used to determine phase angle and gain frequency response parameters for a specimen as it is cyclically loaded. Although the cycles required for specimens to fatigue to failure varies greatly from specimen to specimen, the phase shift between the load and stroke signals as well as the gain of the stroke signal remains fairly constant from specimen to specimen. These characteristic parameters can be used to accurately determine the percent of life remaining and residual strength in other specimens.
