Structure quahty factor

S = basic allowable stress for materials, excluding casting, joint, or structural-grade quahty factors E = quahty factor. The quahty factor E is one or the product of more than one of the following quahty factors casting quality factor Ec, joint quahty factor Ej (see Fig. 10-164), and structural-grade quahty factor E, of 0.92.

There have been a number of previous attempts to relate the appearance of higher harmonics in the transmission of ultrasound through bonded structures to the quahty of the bonds [2-9]. Commonly used is the so-called nonhnearity parameter y 2, a measure of the generation of only the second harmonic [2], and the distortion factor K which describes the complete nonlinear content of the response [7]. In this paper cahbrated measurements on samples consisting of two aluminum plates joined together by a thin epoxy layer are presented and discussed. The amphtudes and phases of the ultrasonic waves transmitted through the bond are considered. The measurements are related to the results of destructive tensile tests of the adhesive layer. 

Hence, the stated above results assume, that the main limiting characteristics of PUAr interfacial polycondensation at other equal conditions are controlled by thermodynamic quahty of organic phase, in which synthesis is reahzed, with regard to polymer. This factor changes macromolecular coil structure, described within the fiamewoiks of fiactal analysis. Fixed in synthesis process coil stmcture... 

As dealt with in the previous section knowledge, responsibility, conflict of loyalty and trust are four important factors affecting the quahty of risk reporting procedures. These factors are imbedded in the organizational power structures, hues of command, and communication channels that constitute the institutional context of risk reporting. And as evidenced, many of these factors contribute to a social or more precisely an institutional attenuation of risk. 

The mechanical properties of ETFE-foils depend on climatic factors (especially temperature), production factors (e.g. foil thickness, or quahty) and loading effects (e.g. load history, load value and rate, time and stress conditions). Taking these factors into account, ETFE-foils exhibit a nonlinear viscoelastic material behaviour. Reasons for this behaviour are the morphological structure and the molecular configuration of ETFE.
