Tension, creep and low cycle fatigue tests were carried out on smooth specimens of polycarbonate at room temperature at strain rate of the order of 10-4/s. Our attention was focussed on the yield behavior of polycarbanate under quasi-static load conditions. The necking and cold-drawing behavior is observed commonly in individual tests. The experiment shows that the creep failure and the low cycle fatigue failure are governed by the tensile properties. On the basis of the yield behavior in tension of polycarbonate, the experimental results of creep and low cycle fatigue tests can be explained, and the limiting condition for creep failure is determined.
