| 摘 要： | 用超声波测试法得到了以混凝土材料参数与声波波速表征的混凝土损伤参量 .将该参量非局部化后代入非局部损伤本构方程中得到混凝土非局部应力与应变关系曲线 ,其方程为一维状态下的混凝土非局部损伤本构模型 .尝试用超声波测试所得的混凝土损伤参数 ,为该问题的解决提供一种方法 ,实验结果表明该方法是可行的 .

| Abstract: | The concrete damage parameters, which are expressed with material parameters of concrete and sonic speeds, are obtained by using the ultrasonic test method. And nonlocalizing the damage parameters and then substituting them to nonlocal damage constitative model, thus the nonlocal stress_strain relation curve is obtained. The equation of the curve is an one_dimensional state nonlocal constitutive model. It provides a solving way for the problem. The test results show that the method is available. |
