The development of the superelement approach applied to models of rod elements

EasyChair Preprint 603

Abstract

The article deals with the rod model for the analysis of stress-strain state of rod structures. Analytical solutions are obtained by the operating method. Unlike the finite element method, defining matrices are formed after obtaining an expression, allowing to calculate the nodal forces through nodal displacements. Examples are given to demonstrate the accuracy of the obtained expressions.

Keyphrases: Boundary nodes, Internal degrees of freedom, finite superelement method, matrix of influence, three-dimensional bar system
