    Sound absorption in metallic foams (1999)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 85 (1999), S. 7528-7539

    Notes: The sound absorption capacity of one type of aluminum alloy foams—trade name Alporas—is studied experimentally. The foam in its as-received cast form contains closed porosities, and hence does not absorb sound well. To make the foam more transparent to air motion, techniques based on either rolling or hole drilling are used. Under rolling, the faces of some of the cells break to form small sharp-edged cracks as observed from a scanning electronic microscope. These cracks become passage ways for the in-and-out movement of air particles, resulting in sound absorption improvement. The best performance is nevertheless achieved via hole drilling where nearly all of the sound can be absorbed at selected frequencies. Combining rolling with hole drilling does not appear to lend additional benefits for sound absorption. Image analysis is carried out to characterize the changes in cell morphologies due to rolling/compression, and the drop in elastic modulus due to the formation of cracks is recorded. The effects of varying the relative foam density and panel thickness on sound absorption are measured, and optimal relative density and thickness of the panel are identified. Analytical models are used to explain the measured increase in sound absorption due to rolling and/or drilling. Sound absorbed by viscous flow across small cracks appears to dominate over that dissipated via other mechanisms. © 1999 American Institute of Physics.

    The damage mechanics of brittle solids in compression (1990)
    Springer
    Pure and applied geophysics 133 (1990), S. 489-521

    ISSN: 1420-9136
    Keywords: Damage mechanics ; brittle fracture ; microcracks ; fracture mechanics ; rock mechanics ; fracture nucleation ; crack growth

    Topics: Geosciences , Physics
    Notes: Abstract The development of microcrack damage in brittle solids in compression is analyzed, using a simple model. The model is developed from recent detailed analysis of the initiation, propagation and linkage of microfractures from pre-existing cracks, voids, or other inhomogeneities. It describes the evolution of damage with strain and from it a criteria for failure can be established. The results are used to construct failure surfaces in stress space which combine information about brittle failure with data describing the onset of plastic yielding. Such failure surfaces are constructed for a number of rocks and are compared with previously published experimental data.

    Plaster of Paris as a model material for brittle porous solids (1993)
    Springer

    Notes: Abstract Plaster of Paris is a brittle, porous solid, easy to shape, which has potential as a model material for the study of brittle, porous, solids such as ceramics, rocks and cement. This paper describes the mechanical properties of plaster of Paris — modulus, strength, fracture toughness, etc. — as a function of porosity. The material is then used to study the initiation and propagation of cracks in compression, as a function of porosity, stress state and stress concentration.

    Properties and uses of consolidated cork dust (1992)

    Notes: Abstract Cork dust was consolidated without additives by heating under pressure. Four engineering properties of the compacted cork were measured: density, modulus, strength and fracture toughness. The thermal conductivity and the absorption of water by the compacted cork were also measured. The properties depend on the consolidation conditions, and (in a way which is not yet understood) on the origin of the cork dust itself, but not on particle size. The properties are compared with those of other common materials to identify possible uses.

    Modulus-maps for amorphous polymers (1986)

    Notes: Abstract This paper explores the possibility of constructing modulus-mechanism maps for amorphous polymers. Four regimes are identified: the glassy regime, the visco-elastic regime, the rubbery regime and the regime of viscous flow (melting), truncated by decomposition. Constitutive laws for each regime are assembled and adapted to give a good description of a large body of experimental data for amorphous polymethylmethacrylate and polystyrene. The adjusted laws are then used to construct diagrams which relate the time and temperature-dependent modulus,E(t, T), to the temperature and the loading time (or frequency). The diagrams are divided into fields corresponding to the four regimes. A diagram summarizes the small-strain mechanical behaviour of the polymer over a wide range of conditions.

    A model for the toughness of epoxy-rubber particulate composites (1980)
    Springer
    Journal of materials science 15 (1980), S. 1109-1123 
    Details
    ISSN: 1573-4803
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract Epoxy resins are toughened significantly by a dispersion of rubber precipitates. Microscopic examinations of propagating cracks in epoxy-rubber composites reveal that the brittle epoxy matrix cracks, leaving ligaments of rubber attached to the two crack surfaces. The rubber particles are stretched as the crack opens and fail by tearing at large, critical extensions. This fracture mechanism is the basis of a new analytical model for toughening. An increase in toughness (ΔG IC) of the composite is identified with the amount of elastic energy stored in the rubber during stretching which is dissipated irreversibly (e.g. as heat) when the particles fail. The model predicts the failure strain of the particles in terms of their size. It also relates the toughness increase to the volume fraction and tearing energy of the rubber particles. Direct measurements of the tearing strains of rubber particles, and toughness data obtained from epoxy-rubber composites, are in good agreement with the model. The particle-stretching model provides a quantitative explanation, in contribution to existing qualitative theories, for the toughening of epoxy-rubber composites.

    Structure and mechanics of the iris leaf (1988)

    Notes: Abstract The structure of the iris leaf resembles that of a sandwich beam with fibre composite faces separated by a low-density foam core. Such structures have a high specific stiffness because the separation of the faces by the lightweight core increases the moment of inertia of the section with little increase in weight. In this paper we examine the structure of the leaf of the bearded iris and show that its flexural stiffness can be explained in terms of the mechanics of sandwich beams.
