Abstract

As for the dynamic problem, some analyses are approximately carried out by use of infinitesimal deformation theory even if large deformations are allowed. Therefore, the limit of applicability of infinitesimal deformation theory need be known. In this paper, the behavior of simply supported beam under collision of impactor with different velocity is analyzed using both theories. So, the quantitative difference between the both results on time proceeds depending on initial velocity of impactor is shown, and the limit of applicability of infinitesimal deformation theory is examined.
