Compressive Strength Basalt Rock

To understand how an extremely lowdensity atmosphere could affect the fracture strength, fracture mode, and strain energy capacity of basalt rock, small cylindrical specimens of the rock were tested in compression in an ultrahighvacuum environment 10 8 to 10 9 torrour groups of specimens were tested in the program 1 specimens tested in air, 2 specimens subjected to.
