Latest Patents

Zhigang Sun's latest patents include two notable inventions. The first is titled "Equivalent acceleration method of creep loads based on consistent failure mode." This patent discloses a method that involves obtaining corresponding tensile strengths and creep rupture times. It establishes laws for rupture time, minimum creep rate, and rupture strain. The method calculates the parameter p in a creep damage accumulation model and divides the failure mode consistency interval of creep load under variable temperature and load. The damage caused by the creep load is calculated using a nonlinear damage accumulation model, ultimately realizing the equivalent acceleration of creep load.

The second patent is "Method for compiling equivalent acceleration spectrum of creep under variable temperatures and loads." This invention outlines a systematic approach to compiling an equivalent acceleration spectrum. It includes conducting high-temperature tensile tests and creep tests under two-stage variable temperatures and loads. The method calculates the damage caused by the creep load spectrum and transforms it into an equivalent acceleration spectrum of a first-order maximum creep load.
