Problems solved by technology

[0006] The technical problem to be solved by the present invention is to address the shortcomings of the above-mentioned prior art. The present invention proposes a calculation method for the volume fraction of the interface around the heterogeneous anisotropic hardened particles. The technical constraints of theoretical research on isotropically hardened spherical particles and the problems of errors and inefficiencies caused by numerical simulations make the calculation method of interface volume fraction more universal and representative

Abstract

The invention discloses a calculation method for heterogeneous anisotropic hardened particle peripheral interface volume fractions. The calculation method comprises the following steps that 1, the sizes of heterogeneous anisotropic particles are defined, and particle size distribution of the multi-particle-diameter heterogeneous anisotropic particles is calculated; 2, volume fractions of a base body are calculated; 3, the average volume and the average surface area of the heterogeneous anisotropic particles are calculated; 4, the number density of the heterogeneous anisotropic particles is calculated; 5, the heterogeneous anisotropic hardened particle peripheral interface volume fractions are calculated. The calculation method shakes off the restraint of the original research technology which can only be used for the simplest spherical particles, and the calculation method for interface volume fractions has higher universality and representativeness.

Description

technical field [0001] The invention relates to a calculation method of interface volume fraction, in particular to a calculation method of interface volume fraction around heterogeneous anisotropic hardened particles, and belongs to the technical field of particle composite medium microcosmic theory and numerical experiment. Background technique [0002] The interface widely exists in various heterogeneous composite materials, and its microstructure characteristics, especially the volume fraction, have a significant impact on the macroscopic mechanical and transport properties of the material. However, it is still impossible to directly measure the interfacial volume fraction in materials by experimental methods. At present, scholars at home and abroad mainly obtain the interface volume fraction information through numerical simulation and theoretical calculation. [0003] In terms of numerical simulation, domestic and foreign scholars usually use the Monte Carlo random po...
