APPLICATIONS / EXAMPLES
Statistical size effect studies
The FREET software integrated with the ATENA software were used to
capture the statistical size effect obtained from experiments.
Probabilistic treatment of nonlinear fracture mechanics in the
sense of extreme value statistics has been recently applied for
two crack initiation problems which exhibits Weibull-type the
statistical size effect:
- Dog-bone shaped concrete specimens in
uniaxial tension (Lehký & Novák 2002);
- size effect of four point bending plane concrete beams due to
bending span
(Novák et al. 2003).
In both cases a good agreement of numerically simulated mean size
effect
curve and an experimental curve have been achieved.
