Additional Finite Elements and Additional Loads for Analysis of Systems with Several Nonlinear Properties

AbstractThis paper dwells upon some problems of formation of additional finite elements and additional loads for analysis of systems having several nonlinear properties that are distinct in nature and time of manifestation. These problems emerge when the Additional Finite Element Method (AFEM) is used. The designed AFEM is a variant of Finite Element Method (FEM) the several units of Method of Ultimate Equilibrium and Method of Elastic Decisions (Method of Additional Loads) to the solution of nonlinear analysis. At the same time, the AFEM develops A.A. Ilyushin's ideas of Elastic Decisions Method for analysis of systems with one nonlinear property and solves the problem of analysis of systems with several nonlinear properties
