    Notes: Abstract Based on the one-dimensional thermo-mechanical constitutive relation of a shape-memory alloy (SMA) in which the dependence of the elastic modulus of SMA upon the martensite fraction is considered, a one-dimensional constitutive relation for SMA-reinforced composite lamina has been developed. The stress-strain relation under constant temperature, the free recovery and the restrained recovery under variable temperature, have been analysed for the SMA-reinforced lamina.

    Notes: Singular finite element displacement functions for linear elastic fracture mechanics applications are investigated. The displacement fields are expressed in terms of polynomials. These polynomials are expanded in varying degrees of r and θ in order to examine the effect of the number and type of terms on the solution to various problems with known solutions. Methods of estimating the stress intensity factors for mode 1 and mode 2 are presented. Numerical results evaluating the effect of various r and θ terms on the solutions are presented.

    Notes: Abstract This paper describes the theoretical analysis, the experimental results and the curve-fitting of the analytical model to the experimental results on the influence of fiber length and fiber orientation on damping and stiffness of polymer-composite materials. The experimental results show that, as predicted, very low fiber aspect ratios are required to produce significant improvements in damping. Measurements and predictions also indicate that the control of lamina orientation in a continuous fiber-reinforced laminate may be a better approach to the improvement of damping than the control of the fiber aspect ratio.

    Notes: Abstract Dynamic impact forces on a composite structure were recovered by using experimentally generated Green's functions and signal deconvolutions. The signal processing is straightforward. Extra windowing and filtering the recorded signals are unnecessary. The Green's functions account for boundary conditions, material properties and structure geometry. This approach can be applied to linearly elastic structures with different boundary conditions. It is realistic and convenient to use for the recovery of impact force on anisotropic or isotropic solid structures.

    Description / Table of Contents: Résumé La méthode de Westergaard conduit à une solution succincte pour les problèmes de fissuration en condition linéaire élastique. On montre ici qu'en superposant les fonctions de Westergaard et un champ de contraintes uniformes uniaxiales, on est conduit à une solution complète des équations d'élasticité linéaire à deux dimensions dans le cas d'un plan infini.
    Notes: Abstract The Westergaard method yields a succinct solution to linear elastic crack problems. Here it is shown that the superposition of the Westergaard functions with a uniform uniaxial stress field provides a complete solution to the equations of two-dimensional linear elasticity for the infinite plane.

    Notes: Abstract Closed form solutions for all three modes of fracture for an infinite piezoelectric medium containing a center crack subjected to a combined mechanical and electrical loading were obtained. The explicit mechanical and electrical fields near the crack tip were derived, from which the strain energy release rate and the total potential energy release rate were obtained by using the crack closure integral. The suitability in using the stress intensity factor, the total energy release rate, or the mechanical strain energy release rate as the fracture criterion was discussed.

    Notes: Abstract When a heterogeneous elastic material is represented by an effective homogeneous elastic solid, average stress and strain fields are used. The meaning of the J-integral in the effective homogeneous solid is investigated. A periodically layered medium is considered. The relation between the J-integrals in the original layered medium and the effective medium is derived.

    Description / Table of Contents: Zusammenfassung Ein zweidimensionales kontinuierliches Modell, das Koppelspannungen einschliesst, ist für gitterverstärktes Verbundmaterial entwickelt. Die Ableitung beruht auf der Berechnung der equivalenten Potentialen und kinetischen Energien des representativen Mediums. Die Bewegungsgleichung und die Randbedingungen sind unter Benutzung von Hamilton's Prinzip entwickelt. Verformungswerte sind definiert und die konstitutiven Relationen sind dann entwickelt. Das Schubschwingungsproblem in der Ebene is untersucht als Anwendungsbeispiel und der Kontinuumansatz sowie ein Elementarteilchenansatz sind angewandt um die Schwingungs frequenzen zu berechnen. Numerische Resultate beider Methoden stimmen ziemlich gut überein.
    Notes: Abstract A two-dimensional continuum model with couple stress for a gridwork-reinforced composite is developed. The derivation is based on the calculation of equivalent potential and kinetic energies stored in the representative medium. Hamilton's principle is used to derive the equations of motion and the boundary conditions. Deformation variables are defined and the constitutive relations are subsequently derived. The in-plane transverse vibration problem is investigated as an evaluation example for which both the continuum approach and the discrete element method are employed to compute the frequencies. Numerical results show that solutions according to both methods agree reasonably well.

    Notes: Abstract Cracked plates subjected to out-of-plane tearing loads were investigated using both classical plate theory and Reissner/Mindlin plate theory. It was shown that the total strain energy release rate according to Reissner/Mindlin plate theory converges to that of classical plate theory as the thickness to crack length ratio approaches zero. It was demonstrated that it is not meaningful to separate mode II and mode III strain energy release rates using classical plate theory.
