An equation describing tablet tensile strength as a function of compaction pressure was derived from the Ryshkewitch and Kuentz-Leuenberger equations. The equation was used to fit data from 11 powders, including single-component powders and mixtures, with a wide range of mechanical properties. Three fitted parameters are obtained directly from tensile strength-compaction pressure data, of which one describes the apparent bonding strength and another strongly correlates with the plasticity.
