Quantitative modeling of quasibrittle fracture. Application to the problem of interaction and coalescence of cracks in polymers

  • Published:
Mechanics of Composite Materials Aims and scope

Conclusions

The results of qualitative and quantitative analysis of the interaction and coalescence of the cracks indicate that the role of these effects in accelerating quasibrittle fracture cannot be controlling. The largest reduction of the strength and endurance of the brittle, bodies is associated with the formation of a single crack of the largest dimension. The appearance of a large number of smaller cracks has only a slight effect on the further reduction of strength and increases the effective cracking resistance.
