Abstract
The deformation behavior of kaolinitic clay green bodies, Kuyama kibushi clay, Georgia kaolin and Kentucky Tennessee clay, was investigated by the uniaxial compression test to determine the formability for the wet-forming process. In accordance with a plastic deformation theory, linear relationships and yield points were observed on stress-diameter/height curves. Below the yield points, the slopes of the stress-strain curves at the initiation of compression were obtained by differentiating the approximation formulas of the curves. Because the slopes were not influenced by the yield points, the deformation behavior of the green bodies below the yield points was considered to be viscoelastic. Since the yield point is related to load during forming and the slope of the stress-strain curve at the initiation of compression is related to form retentivity, the formability of kaolinitic clay green bodies for wet-forming can be determined from the relationship between the yield point and the slope of the stress-strain curve at the initial stage.
