Defining the practical and proper rock failure criteria plays the most significant
role in analysis and design in rock mechanics and rock engineering. Up to now, several
failure criterions have been proposed for brittle rocks. Among them, Hoek-Brown failure
criterion has received much attention and applied among the others for brittle rocks.
The goal of this paper is to investigate the applicability of newly semi-empirical
developed failure criterion inspired by Hoek-Brown failure criteria. To fulfil this
aim, different triaxial test data from literature were selected and analysed for different
rock types. Our obtained results prove the validity of recently proposed formulation
for different investigated rock types.
