Critical levels of oriented defects in brittle fracture

  • Published:
Mechanics of Composite Materials Aims and scope

Conclusions

For an orthotropic system of defects we derived a brittle failure criterion whose coefficients are determined by the parameters of the structure. The discussed examples show that the proposed relationships can be used more efficiently to determine the behavior of the structure on the basis of the macroproperties of the material. The effects of variations in the dimensions of the defects, merging of the defects and the appearance of new defects are described quantitatively. After compiling a sufficient amount of information, the relations can be used to solve the main problem of determining the ultimate strength on the basis of the behavior of the structure of defects.
