| Abstract: | Experiments on the material properties of Q235 steel under different stress-temperature paths were conducted to learn the influence of stress-temperature history on the steel strain. Based on the regression analysis of test data, constitutive relationships of steel materials among strees, temperature and strain under different stress-temperature paths were built. The material properties of Q235 steel that has experienced constant-load heating & cooling and returned to room temperature via natural cooling were also (studied). A comparison was made between the results obtained in this article and that proposed in the papers before. |
