Abstract

In this study, the finite element programs RS2 and RS3 were utilized to simulate the laboratory properties and behavior of pre-cracked (defected) marble specimens, as reported by Yang et al. (2009). The marble specimens contained two, three, or four inclined defects, which were created using a high-speed cutting machine and filled with gypsum. In the numerical models, the defects were represented as joint elements. The objective was to determine a single set of strength and deformation properties for both the intact material (marble) and the joint elements that would replicate the Unconfined Compressive Strength (UCS), Young’s modulus (E), post-peak response and the observed failure mode of defected marble specimens. Model calibration was initially conducted in RS3, and the input parameters from the calibrated RS3 model were subsequently used in the RS2 model. The simulation results showed that both RS2 and RS3, when properly calibrated, can effectively capture the failure mechanisms and mechanical properties of the defected rocks.
