In case one wishes to analyze the defect projections directly the function returns
the projected objects itself. The two types of defects lead to different projected objects.
In case of defect type crack the circle of maximum radius of
the particle is orthogonally projected otherwise the whole particle
is projected in the main load direction, i.e. the xy plane.
getSpheroidProjection(S, type)list of (non-overlapping) particles (spheroids)
either crack or delam
returns a list of 2d ellipse objects.
Get the projected objects (ellipses) of particles dependant on their defect types
