PPT-Nonlinear Analysis:

Overview of Nonlinear Material Analysis Objectives The objectives of this module are to Provide an overview of the nonlinear phenomena that may be encountered in a displacementbased finite element analysis. Nonlinear Model Problem Let us consider the nonlinear model problem 87228711 f in 8486 1a 0 on 8486 1b where is a given positive function depending on the unknown solution As usual is a given source function which we for simplicity assume not to Linear models are easier to understand than nonlinear models and are necessary for most contro l system design methods brPage 2br Single Variable Example A general single variable nonlinear model The function can be approximated by a Taylor seri 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 1 Introduction 23 22 Equilibrium Path and Response Diagrams 23 221 Loadde64258ection response 23 222 Terminology 23 23 Special Equilibrium Points 25 231 Critical points 25 232 Turning points 25 2 Nonlinear Finite Element Analysis Procedures.
