Mechanical Properties of Basalt Cores from DSDP Hole 504B

摘要

Static Young's modulus, ultimate compressive strength, and relative ductility have been measured in both uniaxial and triaxial compression tests on oven-dried, copper-jacketed, cylindrical specimens from basalt cores from DSDP Hole 504B at room temperature and a strain rate of 10 exp -4 s exp -1 . The results indicate drilling rates correlate with both uniaxial and triaxial compressive strengths; compressive strengths also correlate with both static and dynamic Young's moduli of elasticity. P-wave velocity may be useful as a predictor for drilling rates. (ERA citation 08:010811)
