On the fracture behavior of a Zener-Stroh crack with plastic zone correction in three-phase cylindrical composite material

► Interaction of the Zener-Stroh crack with fibers using three-phase model. ► Dugdale model used to introduce a strip of yielded plastic zone at the crack tips. ► Plastic zone size and crack tip opening displacement are evaluated. ► Inclusion volume fraction, load ratio and crack-inclusion distance effects studied.
