Experimental analytical method for quasi-homogeneous material characteristics determination based on elasto-plastic analysis of experimental data

The possibility of material mechanical characteristics estimation based on solving of the elasto-plastic problems for plane with a hole is studied. The proposed experimental-analytical method for the material characteristics determination depends on the analysis of circular hole contour displacement and the sizes of inelastic strains zones near it. It is shown, that three problems can be solved for the material mechanical characteristics estimation according to the assignment of experimental data. One of such problems is considered relating to the rock mechanics. The analysis of this problem solution is made and the scope of its applicability is noted. The validity of similar analysis using for the characteristics determination both of homogeneous and quasihomogeneous material is presented.
