Abstract

Analyses are presented for the stresses and strains developed during drying of gels cast into cylindrical or spherical shapes, using the model developed in Part I of this series. For a given material and drying rate, the tensile stresses decrease in the order plate > cylinder > sphere. This reflects the relative ease of transporting liquid from the interiors of bodies with these shapes. Two solutions are obtained for the cylinder: 1) evaporation from the end and the lateral surface; 2) evaporation only from the lateral surface. The second solution is much simpler, and agrees with the other solution at distances greater than one radius from the exposed end. The solution for the sphere provides a rough approximation to the situation at the end of the cylinder.
