较高应变速率下结构钢屈服强度的估计

Estimatation of Yield Strength of Structural Stell at Various Strain Rates

本文给出了一种考虑应变速率效应时材料屈服强度近似求法，它依据两组低应变速率的拉伸试验数据，对其它应变速率下的屈服强度进行估计，并具有良好的精度。

n approximate approach was introduced to calculate the yield strength of structural steel at verious strain rates with high precision based on two sets of yield strength corresponding to slow strain rates.
