The examination consists of two tests. Compressive loading history was introduced in the first test, to generate five prestrain levels at crosshead speeds of 0.01, 1 and 50mm/min, corresponding to strain rates of 1.85X10'5, 1.85X10'3 and 9.26X10'2 respectively. The second compressive test was carried out two months later, to characterize mechanical properties of specimens including elastic modulus and yield stress, at crosshead speed of 0.01mm/min. Variation of the elastic modulus is used to establish the damage evolution under the compressive loading condition. The results indicate that both yield stress and elastic modulus decrease with the increase of the prestrain. The results also suggest that the extent of decrease of yield stress and elastic modulus, thus the damage evolution, depend on the cro sshead speed applied in the first test.
