Abstract

A formulation is presented for the transient analysis of space frames in large displacement, small strain problems. For purposes of treating arbitrarily large rotations, node orientations are described by unit vectors and deformable elements are treated by a co‐rotational (rigid‐convected) description. Deformable elements may be connected either to nodes directly or through rigid bodies. The equations of motion are integrated by an explicit procedure. Sample results are presented on the snap‐through of an arch‐type structure and an idealization of a vehicle‐barrier impact.

A new approach for numerical analysis of flexible space frames subjected to impact forces is presented. The method is particularly effective in the analysis of large-amplitude vibration and dynamic stability found in extremely flexible structures. The proposed method of analysis is based on a conce
