Abstract: A single-particle breakage model is constructed with material mechanics.Fragmentation of two-dimensional grains under applied pressures is simulated with molecular dynamics.It demonstrates that ultimate grain size distributions follow a power-law distribution with a fractal dimension of about 1.1,which indicates that fragmentation processe of two-dimensional grains is a fractal process.

Key words: single-particle breakage model, molecular dynamics simulation, fractal dimension
