The results are presented of a research project on the mechanical resistance properties and behavior in deformation of macro-particle systems in the light of the theory of the macro-meritic solid, liquid and solution states. A critical analysis and appraisal is made of what goes on in the shear process as a result of design and working features of the test apparatus, as well as of intrinsic properties of the granular system that is under test. The results of this analysis are utilized for the design of a semiautomatic direct shear tester. The historical development of our understanding of the shear process in molecular and macro-meritic systems is traced and an indication is given of how thermodynamic and kinetic-statistical concepts can be fruitfully employed in this continued quest.
