结构修复材料的早期拉徐变研究

Early Tensile Creep of Structural Repair Material

对 3种典型结构修复材料进行了早期拉徐变试验研究 ,并以三元件模型为基础建立修复材料的拉徐变数学模型 .通过试验 ,测定了 3种典型修复材料的拉徐变模型参数 ,从而根据数学模型确定了早期拉徐变及其松弛模量表达式 .模型分析与试验结果吻合良好 。

Three repair materials were tested for their behavior of tensile creep. The mathematical model of tensile creep for repair materials was established based on a three-element model. From the test results and the mathematical model, the factors of the tensile creep model, the early tensile creep and the relaxation modulus of repair materials were determined. A comparison shows that the theoretical values based on the model tally with the test results.
