Abstract
A problem of impact between a structure and a cylindrical falling body is analyzed in this study using three different types of finite element models. A good estimation of the overall displacement of the structure is obtained using two-dimensional simple beam models. To know the local deformation of the structure more accurately, a three-dimensional model is made using beam and shell elements. It is seen from the results of 3-D model that the total displacement of the structure increases due to its local deformation, but it takes a very big CPU time compared to other simple models. This study may, therefore, help to decide and use a suitable analysis model according to the requirement of a particular impact problem.
