摘要：

Crack patterns of drying paste and their statistical properties are investigated through smoothed particle hydrodynamics, which is one method for solving continuum equations in the Lagrangian description. In addition to reproducing a realistic crack pattern, we also find that the average area of a fragment decays inversely with time in the case of linearly increasing desiccation stress. We find that the distribution can be scaled with the average area of the fragment over the corresponding time, even though the distribution function of the fragment area changes the functional form during evolution.
