... of the cracks along the path of either quasi-coplanar or oblique white patches at the two outer flaw tips. A short discussion over the influence of flaw configuration, loading condition and material property will be provided towards the end of the paper, suggesting that different combinations of these factors...

... the rapid decrease in tensile stress after the peak stress. One reason for this problem is the existence of clumps that block the rapid propagation and the connection of the micro-cracks in the model by their interlocking effect. Focusing on the effect of clump configuration on the Brazilian tensile failure...
