Nonlinear analysis of folded-plate structures by harmonic coupled finite strip method and rheological-dynamical analogy

Abstract

This article presents numerical analysis of typical folded-plate structures by the finite strip method (FSM) taking into account geometrical and material nonlinearity. Harmonic coupled FSM is used for geometrical nonlinear analysis, whereas rheological-dynamical analogy for the analysis of softening behavior. The efficiency of this novel method is demonstrated on the structures that are experimentally investigated and described in cited literature.
