Almost-axial impact on an elastic cantilever column—a theoretical study

Slightly slanting impact on an elastic cantilever column—an experimental study

“…The experimental results to be presented in what follows show that for slightly slanting impact (see Figure l(b)), as achieved in these experiments, the main features of impact are similar to those predicted by the theory in reference [7] for almost-axial impact (see Figure l(a)).…”

“…The dimensionless quantities in this paper are the same as defined in reference [7]. (A list of notation is given in the Appendix.)…”

“…stationary body is impacted by a moving column (see Figure 2). In this way one can more easily measure and adjust the small angle of incidence YoThus, the governing equations and boundary conditions of the column, and the conditions of contact between the rigid body and the column are the same as those in reference [7].…”

“…In reference [7] a theoretical model was established for describing the case of almostaxial impact (see Figure l(a)). In such a model the column is impacted by the moving body and the impact velocity V forms a small angle 7o with the axis of the column.…”

“…In reference [7] the almost-axial impact between a rigid body and an elastic cantilever column (see Figure l small angle ")to with the axis of the column. Some typical characteristics of the impact process were obtained.…”
