Elasto-plastic localised responses in one-dimensional structural models
journal contribution
posted on 2023-05-18, 17:47 authored by Coman, CD, Andrew BassomAndrew Bassom, Wadee, MKThis work complements recent developments concerning the buckling of beams lying on a nonlinear (non-convex) elastic foundation, and also reports on some investigations on the role of material nonlinearity. Two structural models are studied using a simple elasto-plastic constitutive relationship, and buckling problems are formulated as reversible fourth-order differential equations. It is demonstrated that modulated responses are possible under certain circumstances. Some numerical simulations are presented supporting the analytical findings.
