Abstract: In the past, deployable structural mechanisms made from pantographic elements of straight struts could form only certain shapes because of restrictions imposed by geometric compatibility conditions, which prohibit the ...

Abstract: In this paper, a 6R linkage suitable as a building block for the construction of large deployable structures is presented. First, we report the possibility of construct an extended 5R Myard ...

Abstract: The microfabric discrete element modeling (MDEM) approach is used herein to predict the asphalt mixture complex modulus in extension/compression across a range of test temperatures and load frequencies. The method allows ...

Abstract: The shape and stress distribution in the new Collapsible Rib-Tensioned Surface reflector are investigated both analytically and experimentally. A methodology is established for the preliminary design of symmetric reflectors ...
