The dependence on the temperature and stress level of PMMA’s crazing damage was researched through the real-time and on-line experiment of PMMA’s crazing damage at different temperatures and stress levels under creep condition. Based on the theory of time-temperature superposition principle, the WLF equation on time-temperature-stress of PMMA’s crazing damage was obtained. By dealing with the experiment data, we got the parameters of WLF equation.
