A hybrid, numerical–analytical model is presented to investigate the transient response of a simply supported elastic–plastic beam subjected to impact of a sphere. The model couples a finite difference model based on the Rayleigh's beam theory wi

The impact response of an elastic-plastic beam is highly complicated in nonlinear transient dynamics especially when the material's plasticity is strain rate dependent. To reduce the efforts required for the computational analysis, an analytical-nume

Repeated impacts of a sphere against a slender beam have been analyzed theoretically and experimentally. The analyses were performed with regard to a repeated impact process of a sphere striking repeatedly at the midpoint of the beam. The impact resu

The normal repeated impact of a sphere upon an elastic-plastic beam has been analyzed experimentally and theoretically. Hertz elastic contact model and seven well known elastic-plastic contact models were selected for theoretical analysis. A piecewis
