The loaded at infinity plate with a central mixed-mode crack is considered. For the piecewise-linear distribution law for cohesive traction, a solution for separations is given and is included in the cohesive zone model with multiple cohesive zone fronts. The governing relationships for critical state parameters are illustrated by numerical solutions for two combinations of the values of tensile and shear external forces.

Keywords: cohesive zone model, complex cohesive zone, mixed-mode fracture crack, traction-separation law
