units, add Fracture Toughness = MPa*m^0.5
Created by: berndhahnebach
I tried to implement a new unit for Fracture Toughness. I would have merged it myself, but the new unit fails :-( ...
>>>
>>> from FreeCAD import Units
>>> getattr(FreeCAD.Units, 'FractureToughness')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: module 'Units' has no attribute 'FractureToughness'
