There are six types of curve possible “Curve type”. First three are valid for Sensitivity

analysis, second three for SINTAP level 3.

−

R curve (CTOD - delta a)

−

R curve (J - delta a)

−

R curve (Offset power law fit parameters)

−

Stress - strain, R-e (Engineering) curve

−

Stress - strain, R-e (Engineering + RO) curve

−

Stress - strain, R-e (True) curve

2.5. Geometry

The geometrical parameters of the crack and component are filled into appropriate

fields shown in Fig. 21. The meaning of the parameters is seen from the picture. One

must consider that geometry parameters cannot take values ≤ 0 and that crack cannot be ≤

0 and it also cannot be greater than the geometrical parameter in which direction it grows.
