property StressEquilibrium.corate

Corotational strain mesure for strain.

Properties defining the way strain is treated in finite strain problem (using a weakform with nlgeom = True) corate can take the following str values:

• “log” (default): exact logarithmic strain (strain is recomputed at each iteration)

• “jaumann”: Strain using the Jaumann derivative (strain is incremented)

• “green_nagdhi” or “gn”: Strain using the Green_Nagdhi derivative (strain is incremented)

if nlgeom is False, this property has no effect.
