.... INTRODUCTION Creep experiments are of paramount importance for assessing the long-term stability of rock engineering structures. ISRM (2007) recognized this issue and a Suggested Method for Creep Test was developed (Aydan et al 2014a). The creep tests have been used in the field of rock mechanics and rock...

... discontinuities and interfaces. The experimental results are presented and the outcomes of this study are discussed in the field of rock dynamics. 1. Introduction Rock dynamics has become one of the most important topics in the field of rock mechanics and rock engineering (e.g., Aydan, 2017; Zhou and Zhao...

... behavior of interfaces such as grout-bar (cable) and grout-rock interfaces. Their mechanical behavior under conventional direct shear, shear creep and cyclic loading conditions were studied experimentally by Aydan (Aydan, 1989; Aydan et al. 1994). These tests were mainly based on the static direct shear...
