Abstract

Abstract

The uniaxial test and Brazilian test have been successfully simulated by using a numerical code named RFPA^2D(abbreviated from Rock Failure Pro cess Analysis).Splitting tensile strengths of ring specimens with different int ernal radius are calculated and compared with others.The influence of internal radius of ring specimen on tensile strength is studied,the best ring specimen for testing tensile strength is determined and the relation between internal radius and tensile strength is drawn out by statistical method.
