Ramberg Osgood unlocked
Some days ago a user in the Prepomax forum (FdoLorenzo) posted a “simple” procedure (Datsko's approach) to calculate the strain-hardening exponent and strength coefficient of a stress-strain behaviour with hardening of the form:
It turns that this is also related to the Ramberg Osgood implemented in ccx. I have derived the final relationship to compute the Ramberg Osgood coefficients just by means of the Yield and Ultimate Strength of a material. It requires ccx 2.21 as previous versions had some issues with the Strain framework.
