Latest Patents

Liu holds a patent for an **Automatic test system for actual stress of a bridge based on DIC technology**. This advanced system comprises a camera, a phosphor spraying device, a computer, and a sliding rail system. The sliding rail is strategically mounted on both sides of the upper wing of a box-shaped concrete beam. The phosphor spraying device applies phosphor to the beam's web, generating speckles of varying light and shade. The camera, attached to the sliding rail via a bracket, photographs these speckles, relaying images to the computer for analysis. This process ultimately produces a time history diagram of the stress, providing vital data for structural assessments.
