COMPUTER SIMULATION OF UNIAXIAL TENSION TEST OF ROCK

Uniaxial tension tests were conducted along with unloading-loading processes. It was found that irrecoverable strain together with compliance gradually increases as failure of a rock sample proceeds. A computer simulation was also carried out and the calculated results was compared with the experimental results.

Key Word : Rock, Tension, Compliance, irrecoverable strain
