In this study we chiefly investigated concerning the characteristics of the stress waves in rocks when they were impacted by detonators and also compared the dynamic stress-strain relation with the static one.
Young's modulus for rocks obtained dynamically was about two or three times greater than that obtained statically. The dynamic strength of rocks was also greater than the static one, but its difference seemed to be not so great as to metals.
Moreover it was an interesting result that various shock effects appeared in accordance with the kind of rocks.
