FIELD: measurement equipment.SUBSTANCE: invention relates to wood science and wood-working industry and deals with assessment of mechanical properties of natural and modified wood. Essence of the invention is as follows: indentation of a puncheon is performed into a solid wood specimen and a cavity is formed. The cavity is made in the form of a ball segment at indentation depth of 0.0007 m<h<0.0029 m, and hardness is determined by formula.EFFECT: providing a possibility of obtaining an overall hardness index representing an integrated hardness value considering anisotropy of wood, methods and methods of its modification, and improving measurement accuracy.1 dwg, 2 tbl |
