Title: THE EFFECT OF PRESHOCK LOADING ON THE RESPONSE OF NTS TUFF

Agency / Branch: DOD / DTRA

Contract: N/A

Award Amount: $50,000.00

Abstract:
PRESHOCKED PRECONDITIONING OF TUFF MAY OCCUR IN TWO MANNERS AT THE NEVADA TEST SITE. FIRST, THE MATERIAL IS "PRESHOCKED" IN A LINEOF-SIGHT TYPE UNDERGROUND NUCLEAR TEST BY THE FIRST WAVE PASSAGE. THE SECOND MANNER MAY OCCUR AS A RESULT OF AREAL SPACE LIMITATIONS WHEN A SECOND EVENT IS SITED WITHIN A REGION OF PRESHOCKED MATERIAL. UNDER CERTAIN LOAD-UNLOADED CONDITIONS THE MATERIAL STRENGTH MAY BE VERY MUCH REDUCED FOR SUBSEQUENT LOADING. A LARGE LOSS OF STRENGTH DUE TO PRESHOCKING COULD SIGNIFICANTLY INFLUENCE THE EFFECTIVENESS OF STEMMING AND CONTAINMENT. A TEST PROGRAM IS PROPOSED ON PROVIDE FOR A BETTER UNDERSTANDING OF THE EFFECT OF PRELOADING (LOAD AND UNLOAD) ON THE MICROMECHANICS OF MATERIAL LOADING AND THE SUBSEQUENT MATERIAL RESPONSE.
