Theoretical study on extension of crack tip plastic zone by remote simple tensile considering crack interaction

In many cases, crack coalescence could be due to the contact of crack tip plastic zone of two cracks. Thus, it is an important work to study the extension of crack tip plastic zone considering interaction of two cracks. Based on the basic theories of famous Kachanov method and with the widely used Mises yield criterion, the extension of crack tip plastic zone by far-field simple tensile considering interaction of two collinear unequal cracks has...
