Basalt is classified as a isotropic rock in according to its mechanical
properties. But gypsum is considered isotropic transverse rock . coming
the mechanical parameters values joins practice direction of parameters
.
By using a nondestructive me
thod such as the ultrasonic test which
depends on understanding the effectual of mechanical properties upon
speed of ultrasonics inside rocks , one can indirectly predict the
mentioned parameters
Tests were completed within 35 gypsum and 11 basalt rocks specimens
which collected by completions under the direction of General
Organization for Land Development ( Directorate of Geological
Investigation).
