Abstract

Highlights: Fatigue behavior of Alvand monzogranite was studied. Maximum stress level and frequency influenced fatigue behavior more than amplitude. Fatigue life increased with increasing frequency and decreasing maximum stress levels. Lateral and axial strain and secant modulus damage parameters showed the best fatigue process. Toughness and hysteresis energy variation show a short decreasing trend phase, dominated uniform increasing phase and short rapid increasing phase.
