Numerical Simulation of the Effect of Loading Angle on Initial Cracks Position Point: Application to the Brazilian Test

The Brazilian Test is the most used test to determine indirect tensile strength for brittle materials like concrete. It has been observed that success of depends on cracks initiation point position and therefore arch loading angle; a crack appears in center disk when valid. To this effect, using Fast Lagrangian Continua code FLAC2D; numerical analyses were performed study impact angle initial crack’s 70 mm diameter concrete mortar under 2α which varies from 5–45°. distribution stresses at obtained numerically was closely similar analytical experimental existing solutions. results showed obtain meaningful validated with accurate strength, it recommended take ≥ 20° 10° mortar.
