根据活断层资料,利用贝塞尔双三次样条模型对中国大陆及其邻区晚更新世以来的平均水平应变率场进行了计算。
Using active fault movement data, we calculated the average horizontal strain rate field of China Continent and vicinity since late Pleistocene with Bessel bicubic spline model.
研究结果表明:特别是在较高平均应变率下,应变率历史对试件材料的应力应变曲线有明显的影响,在材料动态本构关系研究中应当考虑应变率历史的影响。
The results show that the stress-strain curves are significantly affected by the strain rate history, and this effect must be accounted for in the study of material constitutive relations.
