Peridynamic Modeling of Beam Vibration and Impact Damage Concerning Different Deformation Scale

Abstract eng:
A revised bond-based peridynamic approach is proposed to study the beam vibration and impact damage with different deformation scale. In order to predict the beam vibration with small deformation correctly, a surface correction factor is introduced to eliminate the peridynamic inherent “soft” material problem near the boundary. The large deformation induced crack propagation in the beam under impact load is studied subsequently with the uniform peridynamic model. The numerical results indicate that the peridynamic solutions for beam vibration analysis and dynamic fracture behaviour are ahnost identical to the results based on classical beam theory and experimental investigations.
