Modeling Time-Dependent Rock Behavior: Simultaneous Validation of Creep and Stress Relaxation Using a Combined Viscoplastic Approach

This study investigates the time-dependent mechanical behavior of rocks and granular materials, challenging the conventional view of their response as time-independent. We present a rheological model that effectively simulates active loading, creep, and stress relaxation in geomaterials, validated through laboratory...
