    Leaching of 2,4-D and dicamba from home lawns (1988)
    Springer
    Water, air & soil pollution 37 (1988), S. 121-129 
    Details
    ISSN: 1573-2932
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract Leaching of the broadleaf herbicides 2,4-D and dicamba from home lawns was monitored with ceramic extraction plates placed at a 0.2 m depth beneath undisturbed sod. The site was located on a Merrimac sandy loam. Four treatments, consisting of two rates of herbicide applications coupled with two irrigation regimes. were evaluated on 12 plots. The low herbicide rate consisted of 1.1 and 0.1 kg ha−1 yr−1 of 2,4-D and dicamba, respectively. The high rate used was 3.3 and 0.33 kg ha−1 yr−1 of 2,4-D and dicamba applied in three equal applications. Irrigation treatments were (1) minimal irrigation to avoid drought stress and percolation from the root zone and (2) overwatering at 37.5 mm week−1. Geometric mean concentra tions of 2,4-D ranged from 0.55 to 0.87 μg L−1 compared to 0.26 to 0.55 μg L−1 for dicamba. The low application-minimum irrigation treatment generated significantly higher concentrations than the other treatments for both herbicides. The low concentrations observed for both herbicides suggest that excellent degradation conditions exist in the root zone of turfgrass during the summer months when application occurs.

    Application of holographic interferometry to predict long-time torsional relaxation (1975)
    Springer
    Experimental mechanics 15 (1975), S. 153-160 
    Details
    ISSN: 1741-2765
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract The objective of the work described in this paper was to develop techniques to predict long-term relaxation in torsional springs based on short-time data. The torsional springs examined in this study were torsion bars fabricated from 300M steel (280–300-ksi tensile strength). A holographic technique was utilized to perform very precise measurements of relaxation in torsion bars. The technique utilizes real-time holographic interferometry and was capable of resolving relaxation (torque losses) as small as. 01 in.-lb for a bar initially torqued to 825 in.-lb. The holographically determined torque-logs data were used to develop a model to estimate the relaxation behavior of the torsion bars. The model determined to best fit the data is described by: ΔT=0.32(t+50)0.4−qt −1 wheret = time in hours ΔT = total change in torque (in.-lb) The model was developed to fit the holographic data from 0 to 5000 h. Excellent agreement between the torque-loss rate predicted by the model and that actually measured holographically at 10,000 h was obtained. This further indicates that long-time relaxation behavior of the torsion bars can be accurately predicted from short-time tests. Using the model, it is now a simple matter to holographically measure and evaluate the relaxation of other lots of torsion bars to predict their long-time relaxation behavior. The measurement period can be as short as 100 h to show the comparison with baseline data. The long-time prediction can be compared with the acceptable engineering-energy requirements to determine suitability for service.

    Acoustic-emission detection techniques for high-cycle-fatigue testing (1973)
    Springer
    Experimental mechanics 13 (1973), S. 193-198 
    Details
    ISSN: 1741-2765
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract A technique for the study of acoustic emission during high-cycle-fatigue crack propagation has been developed. Difficulties resulting from complex emission behavior and the low signal-to-noise ratio encountered in this type of test are rectified by three methods: minimization of mechanical noise; separation of noise causes according to position in the loading cycle; and rejection of noise from sources other than the crack by a short-time correlation method. The approaches are discussed and data from a fatigue test are presented demonstrating accoustic-emission behavior for crack-growth rates from 3×10−6 in./cycle to 70×10−6 in./cycle.

    Effect of loading variables on the acoustic emissions of fatigue-crack growth (1974)
    Springer
    Experimental mechanics 14 (1974), S. 208-213

    ISSN: 1741-2765
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract A series of experiments has been conducted to determine the effect of loading variables such as cyclic frequency, load ratio, and material on acoustic emission from fatigue-crack propagation. It is shown that the applied-stress intensity range (ΔK) is the controlling parameter for all materials studied while the other parameters have lesser effects. Two potential methods for engineering application of acoustic emission during fatigue loading are described.
