Abstract

Creep behaviors of aeronautic Polymethyl Methacrylate (MDYB-3 PMMA) under different temperatures were experimentally investigated. The creep curves of PMMA at 20°C, 50°C and 75°C and with various stresses were obtained. It was indicated that the duration curves of creep could be divided into three phases. Experimental results showed that the steady creep accumulation speed was increasing with the temperature and stress increasing, and the rupture stretch was increasing accordingly, but the failure time was reducing. The Chen theory, Norton formula and exponential expression were used to describe three phases of creep behaviors respectively.
