摘要
Oblique impact of projectiles onto structures is of importance in engineering. As thefirst step in the theoretical analysis of this problem, an analytical model is proposed in thispaper for a rigid-linear hardening cantilever beam subjected to oblique impact of a rigidprojectile at its tip. This is a "double-hinge model" combining Parkes’ model and Tailor’smodel; and its response is governed by a system of non-linear algebraical equations. Examplesare given to show the travelling of both hinges and the response history of the velocity atthe tip.
