✦ Synopsis

The nature of the response of compact and flexible bodies subject to low velocity impact is studied. The key parameters which govern the response for such impacts are identified and their effects on impact response are examined through numerical simulations. It is shown that three non-dimensional parameters are sufficient to completely govern the low velocity impact response of such structures. By knowing the impact conditions the nature of the response as well as the maximum impact force can be predicted without running a simulation or conducting an experiment. It is also shown that the impact response of different structures with arbitrary boundary conditions can be scaled in a similar way. It is anticipated that the results will be useful in designing for impact loading, in providing guidelines for choosing appropriate simple models and in scaling experimental results between different structures.
