Possibility of clay damage during drying

The convective drying of plate made of clay is considered in the paper. The model of drying with material coefficients dependent on the moisture conte nt and the temperature is presented. The material is assumed to be brittle- elastic (linear elasticity with moisture dependent material constants). The strength of the material estimated by bending test, is moisture dependent. Numerical simulation of drying processes is done. Through the comparison o f the stresses arising during drying with the strength of the material the possibility of dried body damage is shown. The range of constant drying con ditions in which damage is expected is specified.
