Plastic limit loads for cracked pipes under internal pressure containing twin collinear axial through-wall cracks

The paper provides plastic limit loads for tubes with twin collinear axial through-wall cracks under internal pressure. Based on systematic small strain finite element (FE) limit analysis using elastic-perfectly plastic materials, an effect of crack configurations on plastic limit loads are investigated. The obtained values of limit load present coalescence loads of twin collinear cracks. The results are compared to the corresponding plastic limit loads for tubes with a single axial through-wall crack.
