axial rates 中文意思是什麼
-
In the end, we use the constitutive relations with damage and these without damage to analyze the uni - axial concrete compression experiment under different constant strain - rates, so it is validated by mechanical simulation. we find that when the strain - rate is low, we should use the constitutive relations with damage to predict ; when the strain - rate is high, we should use the constitutive relations without damage to predict
針對不同應變率下的單軸壓縮實驗，分別應用考慮損傷和不考慮損傷的本構關系進行力學模擬，發現應變率比較大的時候，混凝土材料可以不考慮損傷；當應變率比較小的時候，混凝土材料要考慮損傷， 。
