 note = {application/pdf, The study of damage pattern growth in brittle material is of fundamental importance for understanding the gestation mechanism and occurring conditions of catastrophe of the great structures. It is especially important in understanding the dynamic catastrophe in rock, such as seismic, rock burst, shock bump, and the three kinds of outburst which are the outburst of water, gas and coal in coal underground mining. In the paper, damage pattern growth in a 2-D sample of heterogeneous brittle material is simulated, which is based on the principle that the damage evolution is irreversible, and the lattice finite element is used for the numeric model. The simulation showed that the complex damage pattern was formed by deduction, which was controlled by the simple dynamic law of the individual element and the strong interaction between elements. The damage pattern grows from dots to lines and to a fractal of which geometry dimension is between lines and a plane., 特集 : 「資源、新エネルギー、環境、防災研究国際セミナー」},
