    Finite-element models of viscoelasticity and diffusion in adhesively bonded joints (1988)

    Notes: The paper contains a description of the finite-element model based on Schapery's non-linear viscoelastic constitutive equation for the adhesive, a non-linear generalized Fickean diffusion model and an updated Lagrangian formulation of a two-dimensional stress state, to analyse adhesively bonded joints. The finite-element analysis program, called NOVA, is used to analyse a number of adhesive joints, and the results are compared with existing experimental results and analytical solutions.

    Instability of jets of arbitrary geometry (1989)

    Description: This paper describes a calculation technique for determining the stability of jets of arbitrary cross section. In particular, elliptic and rectangular jets are considered. The numerical procedure involves both a conformal transformation between the computational domain and the physical plane and a solution of the transformed stability equation in the computational domain. Modern, efficient, conformal mappings are used for both simply and doubly connected domains. The numerical solution is based on a finite difference/pseudospectral discretization of the stability equation. The technique is verified by comparison with previous calculations for circular and elliptic jets. Calculations are performed for the stability of elliptic and rectangular jets of aspect ratio 2. Growth rates, phase velocities, and pressure eigenfunctions are calculated.
