Abstract

The creep behavior of Zeolite molecular sieves has been investigated in this research by using a nanoindentation test. In the holding time, creep curves were obtained. The results show that the penetration depth during constant load phase is time-dependent. After analysis, creep stress exponents of Zeolite molecular sieves were determined from In epsivdot vs .InH curves. Given a secondary creep material model, the indention processes of Zeolite molecular sieves were simulated with the ANSYS finite element code by force loading. The simulative results were consistent with experimental creep curves through modulating the constant C of creep constitutive equation. Therefore, the creep constitutive equations of Zeolite molecular sieves were determined.
