Title: Innovations of Tongfa Deng
Introduction
Tongfa Deng is a notable inventor based in Ganzhou, China. He has made significant contributions to the field of structural engineering, particularly in the detection of fatigue damage and corrosion in concrete structures. With a total of 3 patents, his work showcases innovative methods that enhance the safety and longevity of engineering structures.
Latest Patents
One of his latest patents is titled "Boundary adaptive structural fatigue damage detection method driven by time-domain information entropy." This method involves a sensor sequence that applies excitation to a structure and collects displacement time-history response curves. By establishing a database of time-history data, the information entropy of the time-history response is measured to assess the disorder degree of the signal. The analysis of the time-history information entropy curve helps in identifying the location of cracks in the structure.
Another significant patent is the "Evaluation method for corrosion damage evolution of underwater concrete structures." This method includes conducting time reversal tests on concrete beam specimens submerged in water and performing uniaxial compression tests on concrete cube specimens. By immersing these specimens in hydrochloric acid and evaluating them over time, the method assesses the corrosion evolution process without damaging the underwater concrete structure.
