摘要

PROBLEM TO BE SOLVED: To provide a rod-like body distribution analysis method capable of accurately analyzing a distribution situation of multiple rod-like bodies mixed into a viscous fluid having viscosity.SOLUTION: Steel fiber distribution analysis processing for analyzing a distribution situation of multiple steel fibers 100 mixed into fresh concrete includes: a steel fiber model generation step (step s2) for making the steel fibers 100 into a model by using a steel fiber model 10 in which a relative distance between two particle elements 11 is fixed; a concrete model generation step (step s2) for generating a concrete model Fc which makes the fresh concrete into a model as an aggregate of multiple viscous cells Cv; a fluid motion calculation step (step s3) for calculating motions of the viscous cells Cv in an analysis region S of the concrete model Fc; and a steel fiber motion calculation step (step s5) for calculating motions of the steel fiber model 10 by causing the calculated motions to act on the steel fiber model 10 as an external force.SELECTED DRAWING: Figure 2
