Fracture Process and Failure Mode of Brazilian Discs with Cracks of Different Angles: A Numerical Study

In order to determine the effect of internal cracks on tensile failure materials, a hybrid finite–discrete element method was used analyze Brazilian disc test with different angles. When pre-crack angle is between 0° and 60°, wing crack initiated from end. 90°, center. maximum principal stress plastic strain are concentrated at in As increased mode discs transits splitting into two parts four parts. The influence length further studied. less than 5 mm, has little mode; angles undergoes along loading axis. larger great mode.
