For trusses with large strains, the use of identical material constants in an incremental analysis does not imply identical material behaviors for formulations with different reference states. For consistency, a transformation of the material constants from one formulation to the other based on the continuum mechanics rules is required. In calculating the member forces, it is recommended that the “total form,” rather the “incremental form,” be used at each step to avoid possible numerical errors.
