本文在分析试验获得的不同恒定温度下砼应力—应变曲线的基础上,通过假定,提出了映射温度流动路径,给出了具体的计算公式,并进行了试验验证。
From the analysis of the test results, the method of determining temperature increment path, shining temperature flowing path, is presented and relative formulas are given.
结果表明,流动应力随应变速率的增大而增大,不同温度和应变速率的真应力-真应变曲线呈稳态流动型。
The results show that the flow stress increases with the increase of strain rate, and the true stress-true strain curves at different temperature and strain rates are stable-state.
