... on the better understanding of micro-mechanisms leading to formation of fracture process zone (FPZ) and the following fracture propagation. The interpretation was based on the stress-induced changes in locations and source mechanisms of AEs. As a result, the micro-cracking can be divided into three following...

... INTRODUCTION Three-dimensional (3D) printing is an emerging technology that has garnered increasing interest in the rock mechanics community as it is controllable, repeatable, accurate, efficient, time-saving, and economical (Fereshtenejad & Song 2016, Ishutov 2019 and Kong et al. 2021). It allows researchers...
