The Out-plane Impulse Response of a Curved Bar with Varying Cross-sections

Abstract

This paper is concerned with the dynamic response of a plane curved bar with varying cross-sections under a dynamic load working perpendicular to the plane comprising the center line. As numerical examples, time responses of displacement and bending moment are found for a symmetric semi-elliptic arc bar having varying cross-sections and clamped ends subjected to a step concentrated impact load. The behaviors of responses due to variations of the cross-sections and the load point are clarified.
