In short, one chooses between the stress-strain response to the increasing Load or

Crack. In the first case, the minimum and maximum loads are entered in addition to the

step for increasing the load. In the second, the minimum and maximum crack has to be

entered, including the step for increasing it. The default value of Step for increasing the

Normalized load (

) is 0.02.

3. Assessment

The calculation is initiated by clicking »Start«. There are Critical and Nominal points

obtained by FAD and CDF procedure displayed separately. There are also the Critical

load and Nominal load and crack displayed. If Sensitivity analysis was performed and

automatically set the parameters selected, there are also results of SA visible. An example

of the report is given in Fig. 25.

3.1. Graphical representation of the results

The basic purpose of the SINTAP-FRACTURE MODE procedure and the graphical representation

of the results is assessment of the structural integrity of the component. The location of two points

is determined with the use of a various calculation methods. The first point is called the nominal or

operating point, while the second is known as a critical or failure point. Both are presented in both

graphs (FAD and CDF) and should give identical or comparable results. The position of the

nominal point with respect to the failure curve is of our interest. This describes the failure safety of

the structural component. The failure point expresses the critical state, this state has two

parameters: critical crack length and the failure load.
