Applicability of the recently proposed semi-empirical failure criterion for different rock types by using triaxial test data

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.
