ABSTRACT. It is interesting to investigate the mechanical response of beam under impact load. In this study, the dynamical deformation of an I-sectional cantilever beam is taken into consideration by applying an object falling and the simplified theoretical solution derived from the conservation of energy during impact and the finite element solution obtained by beam element technique are respectively obtained. The comparison is made to show the difference of them. Besides, the effect of impact duration in the finite element simulation is investigated to provide guidance to the implementation of finite element analysis for such impact problem.

Keywords: finite element, Euler-Bernoulli beam, impact, deflection.
