| Abstract: | Based on the ideal assumption that cracks and fibers randomly distribute in cementitious composites matrix and in virtue of the fundamental theory of stochastic geometry and integral geometry,the quantitative relationship between randomly dispersed fibers and cracks is presented in this paper from the viewpoint of fibers/cracks separately.The mutual relationship model of fibers and cracks in matrix is established(namely,the model of multiscale fibers and single disc crack and the model of multiscale disc cr... |
