    Consumer ethics: an application and empirical testing of the Hunt-Vitell theory of ethics (2001)
    Bradford : Emerald
    Journal of consumer marketing 18 (2001), S. 153-178 
    Details
    ISSN: 0736-3761
    Source: Emerald Fulltext Archive Database 1994-2005
    Topics: Economics
    Notes: Analyzes how consumers make decisions involving ethical issues. In particular, investigates the extent to which consumers rely on ethical norms (deontology) versus the perceived consequences of behaviors (teleology) in forming their ethical judgments and in determining behavioral intentions in situations involving ethical issues. The results based upon three studies, including a national sample of adult consumers, reveal that consumers tend to rely primarily on ethical norms and less on perceived consequences in forming ethical judgments. Results also indicate that consumers, to a large degree, rely primarily on ethical norms in determining their behavioral intentions in situations involving ethical issues. Finally, a number of personal characteristics were tested as moderating variables, but results were generally inconclusive, despite some evidence that education and religiosity may be moderators.

    Characterization of the mesostructure of fused-deposition acrylonitrile-butadiene-styrene materials (2000)
    Bingley : Emerald
    Rapid prototyping journal 6 (2000), S. 175-186 
    Details
    ISSN: 1355-2546

    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Fused-deposition (FD) is a robotically controlled "fiber" extrusion process that produces a new class of materials with a variety of controllable mesostructural features related to fiber layout and the presence of voids. Mesostructural features of importance to the stiffness and strength of unidirectionally extruded materials were characterized as a function of the processing variables. Samples were made using the Stratasys FDM1600 Modeler with the P400 acrylonitrile-butadiene-styrene plastic. Results showed that the void geometry/density and the extent of bonding between contiguous fibers depended strongly on the fiber gap and extrusion flow rate. Settings for minimum void and maximum fiber-to-fiber bonding were determined. Void and bond length densities in the plane transverse to the fiber extrusion direction varied from 4 to 16 per cent and 39 to 73 per cent respectively. The results quantify the important mesostructural features as a function of the FD process variables and are expected to find use with other FD materials.

    Mechanical behavior of acrylonitrile butadiene styrene (ABS) fused deposition materials. Experimental investigation (2001)
    Bingley : Emerald
    Rapid prototyping journal 7 (2001), S. 148-158 
    Details
    ISSN: 1355-2546
    Source: Emerald Fulltext Archive Database 1994-2005
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: An experimental study of the mechanical behavior of fused-deposition (FD) ABS plastic materials is described. Elastic moduli and strength values are determined for the ABS monofilament feedstock and various unidirectional FD-ABS materials. The results show a reduction of 11 to 37 per cent in modulus and 22 to 57 per cent in strength for FD-ABS materials relative to the ABS monofilament. These reductions occur due to the presence of voids and a loss of molecular orientation during the FD extrusion process. The results can be used to benchmark computational models for stiffness and strength as a function of the processing parameters for use in computationally optimizing the mechanical performance of FD-ABS materials in functional applications.

    Mechanical behavior of acrylonitrile butadiene styrene fused deposition materials modeling (2003)
    Bingley : Emerald
    Rapid prototyping journal 9 (2003), S. 219-230 
    Details
    ISSN: 1355-2546

    Notes: Analytical/Computational models for the fused deposition (FD) material stiffness and strength as a function of mesostructural parameters are developed. Effective elastic moduli are obtained using the strength of materials approach and an elasticity approach based on the asymptotic theory of homogenization. Theoretical predictions for unidirectional FD-acrylonitrile butadiene styrene materials are validated with experimentally determined values of moduli and strength. For moduli predictions, the results were found to be satisfactory with difference between experimental and theoretical values of less than 10 percent in most cases.
