To explain the dynamics of Velcro-controlled deployment of inflatable structures, we first examine various mechanisms involved in Velcro delamination. Unlike adhesive joints, it is found that Velcro has unique characteristics, wherein multiple load-c

In this paper, the mode localization (ML) phenomenon is investigated experimentally and analytically to determine the influence of its parameters. For this purpose, a full-scale 12-rib loosely coupled antenna testbed with small imperfections is dynam

Active structural members with built-in sensing, feedback control, and actuation functions are used herein, along with passively damped members, to augment the inherent damping in truss structures. The effective use of such members makes it desirable

An approach to combined control-structural optimization aimed at enhancing early design trade-offs is outlined and illustrated by numerical examples. The approach employs a homotopic strategy and is capable of generating families of designs that can

We investigate several approaches to statically assign and schedule the tasks in order to achieve maximum parallelism and minimum communication overhead in both fully-connected and hypercube multiprocessor ensembles. Three simple heuristic techniques

The conditions for and practicability of the stretching of a £lm sheet in a precisely uniaxial and uniform manner by tension cords (“catenaries”) integrated with the sheet edges is investigated. It is shown that kinematic incompatibility between

The DART is a new telescope architecture consisting of two cylindrical parabolic reflectors. The system is ideally suited to using tensioned membranes for the reflective surfaces, owing to the zero Gaussian curvature of a cylindrical parabola.
