2015年7月1日 A damage model for rocks subjected to cyclic stress–temperature was proposed, which applied statistical damage mechanics and continuum damage mechanics. Cyclic stress–temperature tests exhibited superposition of cyclic stress and temperature effects. Basalt specimens were damaged gradually as the cycle number increased, and

basaltic rock minig. Home Page Back . Interesting Fact: Diamonds are extracted from igneous rocks. Kimberlites are extrusive igneous rocks (e.g., a volcanic rock) that transport diamonds from 150-700 km depths in a rare volcanic eruption of kimberlite magma. Luckily, since diamond is the hardest mineral, it can usually survive such rough handling.
