发布时间：2019-04-21 18:12
【摘要】：为得到双材料的本构关系,基于泛形的概念,采用广义泛形Menger海绵来描述双材料中基体和夹杂的分布,可以直接通过泛形测度得到泛形复杂度,且立体模型能够更好地描述双材料的空间结构。进而建立双材料一维泛形立体本构模型,能够体现骨料体积比和级配对弹性模量的影响,给出了等效弹性模量的解析表达式。将其应用于混凝土,数值计算结果与实验结果吻合。
[Abstract]:In order to obtain the constitutive relation of bimaterial, the generalized generic Menger sponge is used to describe the distribution of matrix and inclusion in bimaterial based on the concept of generality, and the generality complexity can be obtained directly by generality measure. And the three-dimensional model can better describe the space structure of two materials. Furthermore, the one-dimensional generalized three-dimensional constitutive model of two materials is established, which can reflect the influence of aggregate volume ratio and gradation on the elastic modulus, and the analytical expression of equivalent elastic modulus is given. It is applied to concrete and the numerical results are in good agreement with the experimental results.
