| Abstract: | A general method for determining the dynamic strain response of an infinite beam to impact force is presented. The method consists of formulating and solving the dynamic problem in the Laplace transform domain and obtaining the strain response by numerical inversion of the transformed solution. Also, an inverse method for estimating the impact force on an infinite beam is investigated. Once the strain is known, it is shown how the impact force can be reconstructed. |
