There are three distinct stages of zinc creep: Primary—the creep strain that happens at a diminishing rate. Secondary—the creep strain that has a minimum and almost constant rate. Tertiary—the creep strain that has an accelerated rate and usually results in rupture.
WebMar 27, 2024 · Results show that under TULCP, the creep strain and the creep strain rate of the K1/J2 PWR exhibits three stages: transient strain, primary creep, and second creep. In the confining pressure unloading (CPU) creep stage, the creep strain increases continuously with the step-by-step of CPU; however, the change in permeability is not monotonic.
