Di64256erentiating 8706S 8706f Setting the partial derivatives to 0 produces estimating equations for the regression coe64259cients Because these equations are in general nonlinear they require solution by numerical optimization As in a linear model The o64260ine phase of the method builds the local red ucedorder bases using an unsupervised learning algorithm In the online phase of the method the choice of the local basis is based on the current state of the system Inexp ensive rankone updates Viscoelastic Material Analysis. Objectives. The objective of this module is to provide an introduction to the theory and methods used in the analysis of components containing materials described by viscoelastic material models.. . . . .
