Notch tip plastic zone determination by extending Irwin’s model

, 2020
With the aid of some explicit formulas of the elastic stress fields at the neighborhood of U- and blunt V-shaped notches and also using the Tresca and Von-Mises yield criteria, the plastic zone size at the neighborhood of such notches under mode I ...

Comparison of Shape Characteristics of Plastic Zone Around Circular Tunnel Under Different Strength Criteria

, 2020
The butterfly plastic zone theory based on Mohr Coulomb criterion has been widely used in coal mine production. In order to verify the universality of the theory, it is necessary to compare the distribution of plastic zone under different strength ...

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

European Journal of Mechanics - A/Solids, 2019
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.
