Symmetry Analysis of the Double Banana and Related Indeterminate Structureses of . distorted bipyramids linked at shared apical vertices). The scalar form of Maxwell’s rule shows only that any states of self-stress and mechanisms of these systems are equal in number, whereas the symmetry extension of the rule shows further that they are either equisymmetric (for odd .) or

Joining of Metal Matrix Compositesoy matrix. Butt joints and joints with attachments are manufactured and subsequently tested in tension to failure. One set of joints is manufactured from aluminum matrix material and another with aluminum alloy reinforced by silicon carbide particles. The initiation of failure in the alloy matrix jo

Elastic Minimum-Weight Design: An Encounter with Alan Turingg for help in proving a general theorem on the optimum design of elastic pin-jointed frames. The manuscript he produced in response to this request appears to have been his only venture into the field of engineering structures: because of his tragic death a year later it was never published. The gen

Prediction of Buckling Load from Vibration Measurementsn mode and the lowest buckling mode are the same. For cases where the two modes are different researchers in the past have suggested some empirical equations. In this study (mainly numerical) it is shown that the linear relationship is reasonably valid when the modes are approximately close to each

Non-Collinearly Loaded Laminaence to the two-dimensional elasticity problem in which rectangular plates (both isotropic and orthotopic) are subjected to the action of non-coilinear but parallel compressive forces (as in a beam subjected to “four-point” loading of its upper and lower surfaces). The work focuses on the case where
