Abstract

The effect of Loading rate on the failure mechanism of rock specimens has been considered in many rock engineering research works, and it has been shown that when the Loading rate rises, the strength of rock specimens increses. İ n the present study, the effect of Loading rate on the breakage process of pre-cracked specimens has been studied using numerical simulations. Extensive numerical simulations of uniaxial compression tests were made using RFPA2D code, and the effect of Loading rate on the failure mechanism of pre-cracked specimens was investigated. Results of experimental tests showed that with an increase in the Loading rate, the length of wing cracks in specimens decreases.
