Abstract

The paper reviews the known consequences of diffusion theory for the mathematical modelling of shrinkage, including the size dependence of drying half-time, and the initial and final asymptotic shapes of the time curves of total moisture loss, to which shrinkage is proportional. The mathematical arguments are extended and presented with greater rigour and generality than before, taking the non-linearity of the diffusion equation as well as ageing into account.
