SUMMARY The anelastic deformation of solids is often treated using continuum damage mechanics. An alternative approach to the brittle failure of a solid is provided by the discrete fibre‐bundle model. Here we show that the continuum damage model can give exactly the same solution for material failure as the fibre‐bundle model. We compare both models with laboratory experiments on the time‐dependent failure of chipboard and fibreglass. The power‐law scaling obtained in both models and in the experiments is consistent with the power‐law seismic activation observed prior to some earthquakes.
