    Description / Table of Contents: Zusammenfassung Es werden Spezialfälle von Wellenbewegungen mit endlicher Amplitude betrachtet, für die keine kinematischen Nichtlinearitäten in den Bewegungsgleichungen des elastischen Festkörpers auftreten. Es kommen also nur Material-Nichtlinearitäten vor. Für gewisse Klassen von Materialien können die Lösungen aus den entsprechenden der linearen Theorie gewonnen werden. Hierher gehören horizontal polarisierte Scherwellen und Lovesche Wellen in geschichteten oder inhomogenen Medien. Es wird gezeigt, daß sich harmonische, zirkularpolarisierte Transversalwellen in jedem kompressiblen oder inkompressiblen elastischen Material fortpflanzen. Einige Effekte homogener Vorspannung werden ebenfalls untersucht.
    Notes: Summary In this paper some special types of finite amplitude wave motions are considered, for which kinematical non-linearities do not arise in the equations of motion of an elastic solid. Consequently, only constitutive non-linearities occur and, for special classes of materials, solutions may be read off from corresponding solutions in the linear theory. These include SH-waves1 and Love waves in layered or inhomogeneous media. Finite amplitude transverse circularly-polarized harmonic progressive waves are shown to propagate in any compressible or incompressible isotropic elastic material. Some effects of homogeneous pre-stress are also investigated.

    Notes: Summary In this paper the uniqueness results found in simultaneous Chebychev approximation are extended to simultaneousL 1 approximation. In particular a sufficient condition to guarantee uniqueness of a best approximate to aL 1 compact set is given.

    Notes: Abstract The affect of substrate roughness and coating thickness on the corrosion resistance of electroless nickel coatings on mild steel in a 0.99M Na2SO4 + 0.01 M H2SO4 + 0.05M NaCl solution has been investigated using electrochemical techniques. The coating was electrochemically more active than pure nickel. The anodic polarization, corrosion potential, and corrosion current depend on the substrate roughness and coating thickness. The substrate roughness decreased for finishes in the order, as-ground, 240 grit, 600 grit, and 1 μm diamond polish, but the corrosion current on relatively thin coatings decreased in the order 240 grit, as-ground, 600 grit, and 1 μm diamond finish. The corrosion potential and the corrosion current of coatings more than about 10μm thick were independent of the surface roughness and similar to those observed with pure nickel. The fraction porosity was estimated to be about 0.005 in a coating about 5 μm thick on a 600 SiC grit substrate.

    Notes: Abstract A plane standing wave solution is obtained for homogeneous, isotropic, incompressible nonlinearly elastic solids. The motion describes the nonlinear interaction of two oppositely propagating, circularly polarized waves. It is used to obtain exact steady state solutions for nonlinear vibrations of a plate and for reflection and transmission of finite amplitude, circularly polarized waves at a plane interface.

    Notes: Abstract Three classes of compressible isotropic elastic solids are introduced, for each of which the strain energy, expressed as a function of the three principal invariants of the stretch tensors, is linear in two of its arguments and nonlinear in the third argument. One of these is the class of harmonic materials. Several deformation fields are examined, for which the governing equations, for general compressible isotropic elastic response, reduce to a nonlinear ordinary differential equation. For the three special classes of materials, this differential equation may be solved in closed form, giving a deformation field which is independent of the material response function, or its solution may be reduced to a single quadrature, involving the nonlinear material response function.

    Notes: Abstract For an important class of incompressible isotropic elastic solids, the response function for the extra stress is a (tensor-valued) function of scalar type. It is shown here that the stress response for compressible isotropic elastic solids cannot be of scalar type.

    Notes: Abstract It is shown that the equilibrium states of Cauchy stress which can exist, in the absence of body force, in every incompressible, homogeneous, isotropic, elastic solid whose deviatoric stress range allows them, must have uniform deviatoric stress invariants. There is at least one such non-uniform stress state. The related problem for incompressible non-Newtonian fluids is also discussed.
