ABSTRACT
It is shown that it is possible to obtain such parameters as and Q, which, when used
in the analytical formulae proposed by O’Dowd and Shih, can lead to stress distributions
similar to those obtained numerically. The numerical solution obtained after calibration of
the stress-strain uniaxial curve and assuming large strains is expected to be close to the
“real” stress distribution. Thus, the analytical solution after correction is also close to the
“real” stress distribution. These new values of and Q can now be used in fracture criteria
proposed within the scope of classical nonlinear fracture mechanics.
