Sažetak
The paper analyzes plastic limit loads for cracked tubes containing twin collinear axial through-wall cracks under internal pressure. Calculations of these loads are based on small strain finite element limit analysis using elastic-perfectly plastic materials. Flow stress as the average value of the yield stress and the ultimate tensile strength was used in the analysis. An effect of crack configurations on plastic limit loads is investigated. The obtained values of plastic limit load present coalescence pressures of twin collinear cracks. The effect of flow stress on coalescence pressure was also investigated. The analysis has been shown that criterion for characterization of the twin collinear axial through-wall cracks into equivalent single crack according to SINTAP procedure is too conservative.
