| Abstract: | The advanced Instron electron hydraulic servo test machine is used to measure the complete uniaxial tensile stress strain curves of concrete. According to the experimental results and collected literatures, with utilization of damage mechanics theory, the appropriate damage equations are deduced and strain softening model of concrete is also established. |
