oa Numerical Simulation of Rock Test for Engineering Properties Using Mesh-Free Method

An element free Galerkin method which does not require connectivity between elements and nodes is examined its efficiency for rock experiment. In this study, uni-axial tensile and compressive tests and collapse of cavity are examined. 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 laboratory tests, and failure mode of the specimen also agrees with general laboratory test results.
