# Fitted Curve !
# Weld metal of SAE1522 or CSA G40.12 structural steel. Bhn 155
# Welding: submerged arc of Oxweld No. 40 wire Linde 36 granular flux
# Tested UoWaterloo David Robins MSc Thesis 1969
# Material cyclicly hardens at high strain ampl., softens at lower levels
# Tensile test: Upper then lower yield behavior
# Data from Heuler/Seeger also conforms to this fitted line well.
