Elastic Analysis of Simply Supported Beam under Impact

Abstract

This thesis presents numerical modelling of discretized simply supported beam under dynamic loading. The beam problem can be efficiently evaluated by devising an analytical problem and then by suitably selecting a computational algorithm for the numerical solution of dynamic problem. The simple beam is envisaged as an assembly of nodes with connected elements in which the mass is lumped at convenient nodes locations. Kinetic and kinematic structural laws are established under the restriction of small displacements in nodal forms. Impact loading, constituting high-intensity dynamic pressures and causing a global dynamic response, is considered.
