Dynamic Buckling in a Rod Having Finite Length Due to Axial Impact

摘要: A pill striking a linear reinforced rod and rigid target are studied. The two critical condition equations achieved. propagation, reflection reciprocity of stress wave considered in the analysis. possibility buckling also analyzed. At last, specific material is used to carry out numerical calculations from which relationship between impact position obtained. flight velocity slenderness ratio arrived at. These conclusions important dynamic experiment finite elastic plastic rod.
