| 中文摘要 | Two-dimension spring square network model involving the nearest and second neighbour bonds is studied by numerical simulation with Gauss-Seidel iteration for brittle fracture Mode 1. The material-dependent parameter, G(0)/G, is introduced in this simulation, G and G(0) are the parameters related to the elastic moduli of the nearest and second neighbour, bonds, respectively. Brittle fracture of materials with different G(0)/G are simulated under the same quenched disorder. The fractal dimension of crack fluctuates with G(0)/G. It seems that it is impossible for different materials to have a universal fractal dimension of crack in brittle fracture. However, it is possible to have different so-called universal fractal dimensions. (C) 2003 Elsevier Science B.V All rights reserved. |
