A method of determining joint stiffness degradation in structure is provided including a first exciting of the structure a first measuring of transfer function and frequency response function simulating a mileage accumulation process of the structure performed after the first exciting and the first measuring a second exciting of the structure performed after the simulating a mileage accumulation process a second measuring of frequency response function performed after the simulating a mileage accumulation process and calculating the change in joint stiffness using the first measuring and the second measuring

Method for determining joint stiffness degradation

A method of using a microscopic digital imaging strain gauge includes the steps of creating a mark pattern on an object surface, positioning an image sensing device over the mark pattern, magnifying the mark pattern with a magnification lens, taking a first magnified image of the mark pattern with the image sensing device, applying a load to the object surface, taking a second magnified image of the mark pattern, and utilizing a processor to calculate the strain as derived from the first and second magnified images.

Method of using a microscopic digital imaging strain gauge

A strain gauge includes an image sensing device having a lens, a magnification lens optically coupled to the lens, a positioning mechanism connected to the image sensing device, an image capture device for receiving an image from the image sensing device, and a processor for mathematically analyzing the image received from the image capture device and to calculate strain.
