METHOD FOR DETERMINING SPECIFIC SURFACE ENERGY OF DESTRUCTION OF SOLID BODIES |
摘要 |
FIELD: mining.SUBSTANCE: specific surface energy is determined as per a diagram of specimen deformation at forward and backward travel. A start cross fracture is made on the specimen; distributed force is applied to the opposite side plane; the above side planes are fixed by compression between parallel stiff elastic bases, and longitudinal compressive force is applied to the specimen end faces above the area of the middle surface above the fracture.EFFECT: high accuracy of experimental determination of specific surface energy of destruction of solid bodies on specimens in laboratory conditions.2 cl, 1 ex, 3 dwg |
