Abstract
A transmission line matrix model of viscous bending under gravity is devised. This is initially extended to a two‐component, parallel, dashpot‐spring model corresponding to a Kelvin solid, and then to a three‐component model comprising an initial elastic deflection followed by a slow viscoelastic deformation. This three‐component model is used to predict the deformation of thin walled ceramic shapes during firing. Predicted deformations and those observed in fired ceramic pieces are compared for three types of ceramic shape; bars supported as cantilevers, vertical hoops and three‐dimensional ‘mushroom’ shaped shells.
