Abstract

An element free Galerkin method which does not require connectivity between elements and nodes is examined its efficiency for rock experiment. In this study, unconfined compressive test and biaxial test are performed. In this process, the rock specimen is assumed to heterogeneous assigned by Weibull distribution. Acoustic Emission which is microscopic behavior of the specimen agrees with UCS. And failure mode of the specimen also agrees with general laboratory test results. Next, macroscopic behaviors of the specimen which is Young’s modulus, UCS, cohesion, internal friction angle are examined unconfined compression test and bi-axial test. These macroscopic parameters show the tendency has been to increase with an increase in shape parameter.
