Dimas, D.M. and Guedes Soares, C. (2004), “Energy Absorption and Rupture Analysis in Small-Scale Beams under Transverse Impact”, Proceedings of the 3rd International Conference on Collision and Grounding of Ships (ICCGS 2004), 25-27 October, Izu, Japan, pp. 312-321
Numerical studies performed of the clamped beams under transverse impact of moderate speed at different points along its span are described here, and are compared with the experimental ones, showing good agreement. For clamped beams under transverse impact, three basic failure modes were identified; large inelastic deformation (Mode I), tensile tearing (Mode II) and transverse shear failure (Mode III), or mixed modes of failure. Two types of elements were used in this study and their results were compared the results are given in terms of the energy absorption in the mild steel as a function of the incident velocity and the contact force versus displacement.
