Stationary creep prediction from model tests using reference stresses

The theoretical basis of the experimental determination of reference stresses from model tests is established for one-dimensional and complex stress systems. A graphical method of obtaining the experimental reference stress is presented and used to determine reference stresses for the strain in beams in pure bending and the tip deflection of cantilever beams from room-temperature tests of lead-antimony-arsenic models. The results are compared with theoretical values. It is shown how prototype deformation can be predicted from a test of a model of the component, model material creep data and the strain of a uniaxial prototype material specimen tested at the reference stress. Errors in the prediction of prototype deformations are considered.

Improved upper and lower bounds for deflections of orthotropic cantilever beams

Formulas for upper and lower deflection bounds, in terms of appropriately applied approximations to potential and complementary energy expressions, are evaluated on the basis of variational problems which involve fourth-order ordinary Euler differential equations, with associated Euler and constraint boundary conditions. The paper obtains new information on the order of magnitude of effects which modify the results of elementary beam theory through the influence of transverse shear and normal strain deformations, including the delineation of boundary layer effects, with one or two such layers, depending on the degree of orthotropy of the material of the beam.

An Analysis of Large Deflection of the Circular-Arc Cantilevers and its Application for the Laminated Springs

The classical theory of deflection of beams neglects the square of the first derivative in the bending moment equation, and cannot be used when the slopes of the beames are large. This paper deals with large deflection, by slanting and concentrated forces, of initially circular and uniform beam. Both the strict and approximate solutions of this problem are derived, and the scope of application of the latter is sought. In addition, the approximate solution for large deflection of circular-arc and trapezoidal cantilever beam is given by the use of series, and it is applied to the calculation of the deflection of a laminated spring with a shackle, and the considerable agreement with experimental value is confirmed.
