Abstract

INTRODUCTION A study of Elastic Constants and their applications led to the conclusion that the dynamic values are more valid for solutions of rock mechanics problems. After investigation it was found that the equations for Shear Modulus, Young’s Modulus, Bulk Modulus and Poisson’s Ratio could be related to log derived values of density, shear travel time and compressional travel time. It was also apparent that values for elastic moduli determined from log derived data are suitable for use in rock mechanics problems.
