| Abstract: | Through an analysis on the practical complexion of the fibre distribution for the fibre reiforced concrete, the mathematical stochastic processing model of the fibre distributing is established based on the stochastic mathematics principle and the stereological principle. The dynamic fibre transfer processing is investigated, and the computer testing system for dynamic steel fibre distributing mesoscopic geometry parameter is authorized. What's more,the mesoscopic geometry parameter and the mesoscopic mechanism for the fibre distribution are studied, thus, three dimension fibre distribution is simulated. The findings show that the fibre distribution is stochastic and the mathematic model best displays the practical complexion of the fibre distribution. |
