摘要
采用非线弹性本构模型,根据高强混凝土单轴动态抗压强度、弹性模量与应变速率的相关关系式,引入应变速率修正系数对类似的本构模型进行修正,进而建立高强混凝土的单轴动态抗压本构模型,并应用试验数据对修正的本构模型进行验证。
This paper adopts the non-linear elastic constitutive model, bases on relationship types of high strength concrete to uniaxial dynamic compressive strength, elastic modulus and strain rate, introduces strain rate correction factor for a similar amendment to the constitutive model, then establishing a constitutive model of high strength concrete to uniaxial dynamic compression, and apply experimental data to verify the correctional constitutive model.
