... fidelity is developed to acquire the derivatives of displacements with respect to constitutive parameters, which are required for the accurate and stable gradient based inverse analysis. A two-step strategy is presented in the process of identification, by which the unknown parameters can be separately...

... prognostics health management. Findings In result, the regression model discovered by GP can identify the state of tool wear. Compared to other regression algorithms, e.g. support vector regression and polynomial regression, the identification of GP is more precise. Research limitations/implications...

..., 2004). A presented identification method of hardening parameters, from spherical indentation tests that were performed and followed the Mises yield criterion and isotropic hardening, was assessed by comparing the predicted and measured stress–strain curves (Kucharski and Mróz, 2001). Cao and Lu (2004...

...O. Allix; P. Feissel; H.M. Nguyen Purpose To propose and develop an identification method of material parameters from dynamics test in the presence of extensively corrupted measurements. Design/methodology/approach The method we propose, which is based on the use of the error in constitutive...
