Calculate critical area

1	areaCrit(vickers, stress, factor = 1.56, scale = 1e+06)

`vickers`	specific Vickers hardness
`stress`	stress level to be applied
`factor`	specific material dependant factor, default set to `1.56` for inner defects
`scale`	scale factor, area in square millimeters (default)

The critical area (see reference below) is roughly defined by the projected defect area above which the specific material defect becomes particularly hazardous for the failure of the whole specimen.
