与传统的预应力钢筋相比，AFRP筋材的短期力学特性主要有：（1）应力-应变关系近于直线，没有屈服点；

AFRP reinforcement have two characteristics of short-term mechanical behavior compared to steel bars : ( 1 ) Tensile stress-strain curve is close to a straight line and have no yielded point ;

随着共混物中DP含量的增加，材料性质逐渐从弹性转变为塑性，屈服点出现，屈服和断裂强度增加，结晶度逐渐提高，伴随着相转变的发生。

With DP content increasing , yield point of the blends occurs and yield strength and strength at break gradually increase , indicating the gradual transition from elastomeric to plastic properties as a result of the phase invertion and elevation on the crystallinity of the blends as DP is added .

计算结果表明，对于超固结土，固结阶段内的非线性流变特性要更加明显；采用非线性流变模型能够更好的模拟Imai等（1992）采用特殊压缩试验得到的屈服点现象。
