    A calculation of the bulk modulus of polycrystalline materials (1989)
    Springer
    Journal of materials science 24 (1989), S. 4265-4267

    Notes: Abstract It is shown that the bulk modulus of a polycrystalline material, composed of cubic single crystals, is the same as that of the constituent single crystal. The bulk modulus of the aggregate is independent of the distribution of the individual single crystals. The same results apply also to other polycrystalline systems, whose constituent single crystals undergo a pure uniform contraction when subjected to hydrostatic pressure.

    Internal pressure test for characterizing fast-fracture reliability of grinding wheels (1992)
    Springer
    Journal of materials science 27 (1992), S. 3719-3725

    Notes: Abstract A constant danger associated with the use of most grinding wheels (vitrified-bond alumina and silicon carbide wheels) is the possibility of fracture during operation. A standard practice is to subject newly manufactured wheels to a spin test and accept wheels that survive. We propose an internal pressure test which offers a simpler, more economical alternative to the spin test for testing grinding wheels. Probabilities of failure in the internal pressure test are correlated with failure probabilities in the spin test using probabilistic fracture mechanics. Results indicate a reasonably good correlation between the two tests, thus demonstrating their equivalence. A scheme for the easy implementation of the internal pressure test to detect damage in grinding wheels is outlined.

    An elastic-viscoplastic constitutive model for the hot-forming of aluminum alloys (2000)
    Springer
    Journal of materials science 35 (2000), S. 3647-3654

    Notes: Abstract Under hot-forming conditions characterized by high homologous temperatures and strain-rates, metals usually exhibit rate-dependent inelastic behavior. An elastic-viscoplastic constitutive model is presented here to describe metal behavior during hot-forming. The model uses an isotropic internal variable to represent the resistance offered to plastic deformation by the microstructure. Evolution equations are developed for the inelastic strain and the deformation resistance based on experimental results. A methodology is presented for extracting model parameters from constant true strain-rate compression tests performed at different temperatures. Model parameters are determined for an Al-1Mn alloy and an Al-Mg-Si alloy, and the predictions of the model are shown to be in good agreement with the experimental data.

    Stress intensity factors for a crack in planar disking (1993)
    Springer
    International journal of fracture 60 (1993), S. 19-32

    ISSN: 1573-2673

    Notes: Abstract Disking is a relatively new manufacturing process for cutting/slicing brittle plates and rods. In the planar disking configuration, a pre-cracked plate is placed against an elastic plate and the two are squeezed together by fluid pressure. At a critical pressure the crack runs across the thickness of the brittle plate producing a clean cut. In this paper a fracture criterion is developed for the process using linear elastic fracture mechanics. The geometry of the process is modeled here as two perfectly bonded, infinite elastic layers with a crack perpendicular to the interface. The problem is formulated in terms of a singular integral equation with the derivative of the crack surface displacement (dislocation density) as the unknown function. Numerical quadrature is used to determine the stress intensity factors as a function of the parameters of the problem.

    Fracture criterion for the axisymmetric disking process (1993)
    Springer
    International journal of fracture 60 (1993), S. 65-77

    Notes: Abstract Disking is a process designed to cut brittle plates and rods. In axisymmetric disking, a pre-cracked cylindrical rod is placed in an elastic, annular sheath and the composite is subjected to biaxial fluid pressure. At a critical pressure the crack runs across the circular section of the rod producing a clean cut. A linear elastic fracture mechanics analysis is used to develop a fracture criterion for the process. A concentric circular cylinders model is assumed with perfect bonding at the interface. The flaw that initiates fracture in the rod is modeled as an annular crack perpendicular to the interface with one crack tip at the interface. The problem is formulated as a singular integral equation of the first kind with a Cauchy type kernel. The stress intensity factors are determined as a function of crack size and shear moduli.
