Suppose again that both the stress and strength distributions of interest are of the Normal type, where the loading stress is given as L A (350,40) MPa and the strength distribution is S A (500, 50) MPa. The Normal distribution eannot be used with the integral transform method, but ean be approximated by the 3-parameter Weibull distribution where the CDF is in elosed form. It was determined above that the loading stress parameters for the 3-parameter Weibull distribution were ...

Indirect determination of the yield stress simply involves extrapolation of the experimental shear stress-shear rate data to obtain the yield value as the shear stress limit at zero rate of shear. The extrapolation is performed numerically on the available data, or the latter can be fitted to a suitable rheologic model representing the fluid, and the yield stress parameter in the model is determined.

It follows that for plane-stress parameters Gc and Kc have been replaced by the plane-strain parameters Gic and KIC which are in general smaller than their plane-stress analogues. 

In peptide/protein pharmaceuticals, the GAS process is predominantly applied for the preparation of microparticulate protein powders as an alternative to common drying processes. However, Winters et al. [69] reported an increase of P-sheet aggregates during the precipitation of lysozyme, trypsin, and insulin as a consequence of stress parameters such as organic solvent, pressure, and shear forces. One reason... 

Actually there are defined no minimum requirements for the stability or the dynamics of the hydrophobicity of silicone elastomers. The presently existing knowledge has been achieved from long-time field and laboratory tests. Because of the complexity of the stress factors, the results are not always comparable. Thus, systematic laboratory experiments have to be performed to be able to validate the influence of different material parameters. This paper deals with experiments on the influence of single stress parameters on the hydrophobicity. The results are compared with the electrical behavior of droplet layers on the silicone mbber surfaces. 

The results presented here are adapted from a detailed investigation of the stress splitting of some S- and Se-related donors in silicon [14]. At a difference with the centres considered in the preceding section, the separation between the Is ground state and the EM-like Is states of the deep donors precludes a stress-induced interaction between these states. The experimentally-observed shift rate with stress of a transition is the difference between the shift rates of the excited (e) and ground (g) states, defined by the invariant operators Va1 = -j- (Vxx + Vyy + Vzz) which, for degenerate excited states, affect only their centre of gravity. The transition stress parameter Ai is defined as ... 

The effect of stress on the transitions from the deep ground state to EM excited states can be seen as the superposition of a DP contribution similar to the one for the cubic centres and of a ground-state contribution due to orientational degeneracy, characterized by a transition stress parameter A2. The combined shift and splitting of the ground state of a deep donor centre...

Then we will consider the other power components. We will point out which particular stress parameters are important in each case, and also the input voltage at which they reach their maximum, and how to ultimately select the component.
