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

EasyChair Preprint no. 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, finite superelement method, Internal degrees of freedom, matrix of influence, three-dimensional bar system
