Abstract
The paper addresses the nonlinear dynamics of a hinged simply supported beam with an axial elastic support. The investigation is based on the Multiple Time Scales Method (MTSM) applied directly to the governing partial differential equations of motion, and is focused on the first seven bending resonances of a planar system. The effect of axial spring on hardening/softening phenomena is illustrated. Backbone Curves (BbCs) and Frequency Response Curves (FRCs) for selected cases are shown and compared with their numerical counterpart done with the Finite Element Method (FEM) to cross-checking the reliability of analytical and numerical methods.
