Estudo do rompimento de fios sob a ação de impactos de tração

Abstract

In the present work we analyze the rupture of metallic wires under the action of stressing impacts. We have collected experimental data in order to relate the mass M and speed V of the body causing the stressing impact in a wire on the threshold of rupture. By making use of II-Buckingham's theorem of dimensional analysis we have determined an expression for the function M = F(V ) and have compared it to simplest possible model of the phenomenon and verified that it is compatible with experimental data.
