Abstract
The purpose of this work is to develop an express method of evaluating the coefficient of internal friction and cohesive strength of molding material briquettes. Advantages and disadvantages of modern evaluation methods of internal friction parameters in particulates have been considered, and the need to improve them has been substantiated. An alternative method based on measuring the position of shear planes and the briquette cracking pressure in uniaxial compression strength tests has been proposed. The theoretical justification of the method has been provided, and examples of implementation have been given. The research results may be used in the process of educating students of technical specialties, as well as at research and design organizations.
