Abstract:
Based on the phenomenon of "split brick by Qigong", a mechanical model for short beam impact is proposed. Combined with the traditional energy method, a theoretical analysis of the impact of the short beam (Timoshenko beam) closer to the real situation is made considering the quality and initial deformation. The optimal solution of short beam impact problem of how to choose the position where the short beam is most likely to break is obtained. The finite element numerical analysis and experimental test are used, and the results verify the applicability of the theoretical analysis of the proposed model.
