Compliance effect

Other SFA studies complicate the picture. Chan and Horn [107] and Horn and Israelachvili [108] could explain anomalous viscosities in thin layers if the first layer or two of molecules were immobile and the remaining intervening liquid were of normal viscosity. Other inteipretations are possible and the hydrodynamics not clear, since as Granick points out [109] the measurements average over a wide range of surface separations, thus confusing the definition of a layer thickness. McKenna and co-workers [110] point out that compliance effects can introduce serious corrections in constrained geometry systems. 

Numerous surveys, for example, Calfee (2002) and Aikin (2003), have reported that both patients and physicians perceive DTCA to improve adherence to recommended treatment. Yet there is unfortunately relatively little empirical evidence on the magnitude ofthis compliance effect. More important are impacts of DTCA, if any, on patient outcomes. Two recent studies have provided indirect evidence.

FIGURE 14.6 A vascular occlusion produced by reducing the input pressure to zero for 2 sec. The flow response transients are due to compliance effects. Flow increases to maximum value corresponding with complete vasodilation. A damped oscillatory response returns the flow and resistance to control levels. 

Depending on whether the traverse path or the extensometer or a clip gauge is utilized to eliminate compliance effects from the testing machine (grips and load cell), either Eq. 4.2 or 4.3 has to be used to calculate strain. From the derivation of strain with time, one can obtain normative strain rate (Eq. 4.4) or nominal strain rate (Eq. 4.5) in the deformed volume d8 /dt ...

There are some specific terms and definitions used in the ADA. Employers need to become familiar with these terms in order to manage ADA compliance effectively. 

Effects of instrument compliance can induce large errors on shear measurements of elastic and viscoelastic properties of materials [1,2]. These effects are caused not only by the transducer but also the machine itself (load frame), and the rheometer fixtures. We present examples of rheometer compliance effects on the measurement of the material properties of small molecule glass formers and a commercially available polydimethysiloxane (PDMS) rubber. A TA Instruments ARES Rheometer was used with a strain gage transducer (Honeywell-Sensotec). Stress relaxation, aging experiments, and dynamic frequency sweep experiments were performed. We also propose a procedure to correct for comphance effects in stress relaxation experiments and dynamic frequency sweep experiments. Suggestions are made for both instrument and experimental design to avoid and/or reduce compliance effects. 

Using much the same methodology, shear stress relaxation data can be corrected for instrument compliance effects. In a stress relaxation experiment, usually there is a commanded step in strain that is imposed on the sample. The resulting torque is then measured. If the instrument is compliant, not only does the sample twist (for torsion experiments) but the machine also twists. These results in a lesser strain applied to the sample. Referring to reference [6], we have the following ...
