Abstract
A revision to a previously developed method for solving the dynamic‐contact problem of a rigid, smooth striker impacting an elastically supported beam is presented. The revision is such that only a local‐static solution is superposed on an elementary‐beam‐theory solution that incorporates the dynamic effects. The local‐static solution is expressed in terms of the difference between an elastic‐finite‐layer solution and a static‐beam‐theory solution. The matching of boundary conditions leads to a Volterra‐integral equation of the second kind in terms of the pressure distribution and contact length as functions of time. These quantities are obtained numerically using a technique developed for the solution of non‐Hertzian‐contact problems. The revised method is shown to more accurately model the low velocity impact response of finite beams through a comparison of experimental results and theoretical predictions.
