摘要
耐腐蚀性好、比强度高的FRP材料应用于各个领域,为研究其动态本构模型,文中将从两个方面(细观力学方法和宏观唯象方法)来叙述。将细观力学方法分为粘弹性本构模型和桥联模型两个模块进行描述;宏观唯象方法分为正交各向异性材料本构模型、含损伤率相关本构模型和其他本构模型3个模块进行描述;最后将本构模型进行简单的对比。
With good corrosion resistance and high specific strength,FRP materials are used in various fields.This paper studies the dynamic constitutive model of FRP materials by meso-mechanical method and macroscopic phenomenological method.The mesomechanics method is divided into viscoelastic constitutive model and bridging model.The macroscopic phenomenological method is divided into orthotropic material constitutive model,damage-related constitutive model,and other constitutive models.Finally,the constitutive models are compared.
