ACKNOWLEDGEMENTS
The authors gratefully acknowledge the financial support from the Serbian Ministry of
Science under the project OI 144027 and Slo-Serb. bilateral project "Failure prevention of
inhomogeneous materials and structures" (together with Slovenian Ministry of Science).
The lecturers would also like to thank N. Gubeljak for the results of the tensile and
fracture mechanics tests, Z.L. Zhang for the CGM user subroutine, M. Dobrojević for
useful suggestions and I. Cvijović - Alagić for help in microstructural analysis.
