...Peter J. Ryan; George G. Adams; Nicol E. McGruer In beam theory, constraints can be classified as fixed/pinned depending on whether the rotational stiffness of the support is much greater/less than the rotational stiffness of the freestanding portion. For intermediate values of the rotational...

... to a system parameter is then presented for structural damage detection. A numerical example with a 31 - bar plane truss structure is used to verify the proposed method with different damage scenarios with or without model error and noise effect. 03 02 2005 03 02 2006 bars supports...

... predictions and suggest that hierarchical corrugated cores have a high potential in strength limited sandwich panel applications. We are grateful to the Office of Naval Research for support of the work reported here under Grant No. N00014-01-1-1051 (program manager, Steve Fishman). The authors would...

... deflections. The theoretical predictions of structure weight, deflection, and support reactions are shown to be in close agreement to the values obtained with truss designs, whose nodes are spaced along the theoretical spiral layout lines. The original Michell solution based on 45 deg equiangular spirals...

... to actuation is presented as an additional constraint. The ensuing relations are subsequently used to choose the best material for a given application. Numerical examples of the procedure are given for a defined structure. 23 07 2004 14 02 2004 plates (structures) supports Young's modulus...
