Analytic Models

Analytic models that describe the mechanical behavior of thin glass–polymer laminate structures have been investigated experimentally and via finite-element analysis (FEA). Standard laminate effective thickness models were shown to be applicable to a wide range of glass/interlayer thickness ratios and to a wide range of interlayer shear moduli, covering most currently existing glass laminates. In addition, an analytic comparison of the effective thickness model with the traditional composite beam model clarified the applicable limits of the former model in the range of the interlayer/glass thickness ratio and interlayer shear modulus. These modeling approaches enable a rational engineering design approach for structurally efficient, lightweight, and safe glazing laminates.

The term ultimate resolution or resolving power is the very best performance that can be obtained from a scanning electron microscope (SEM) given the optimum instrumental conditions and sample. However, as it relates to SEM users, the conventional definitions of this figure are ambiguous. The numbers quoted for the resolution of an instrument are not only theoretically derived, but are also verified through the direct measurement of images on micrographs. However, the samples commonly used for this purpose are specifically optimized for the measurement of instrument resolution and are most often not typical of the sample used in practical applications.SEM RESOLUTION. Some instruments resolve better than others either due to engineering design or other reasons. There is no definitively accurate definition of how to quantify instrument resolution and its measurement in the SEM.
