TAGGED: curve-fitting, hyperelastic, residual
March 21, 2023 at 12:16 pmKraehn_BSubscriber
Greetings to all,
I am currently performing parameter identifications for different hyperelastic laws. Looking for the definition of the residual calculation expression, I only found this explanation in the ANSYS help : "The error norm can be set to use normalized or absolute error. Normalized error norm considers each experimental datum equally in computing the curve fit. It generally provides better results than the absolute error norm, but in some cases the absolute error norm is a better choice.".
Is the exact expression of this parameter (normalized or absolute error) given somewhere?
Thank you in advance for your time,
