# Room Temperature & Air Environment.  Only the fully reversed tests shown here.
# Ref: Thesis and SAE paper 930752 Mag. has very odd hyst. loops.
# (Cyclic modulus on all short life tests is very low ~ 3600 to 4500)
# Changed E from 6500 to 5500 to improve fit of cyclic S-e)
# Changed to calculated Plastic Strain
