Structured model, strength properties

It is easy to see that these models are all based on the same (microstructural) principle, viz. that there is an elementary structural unit that can be described and then used for calculation. Remember that the corresponding unit cell for foamed polymers is the gas-structure element8 10). Microstructural models are a first approximation to a general theory describing the deformation and failure of gas-filled materials. However, this approximation cannot be extended to allow for all macroscopic properties of a syntactic foam to be calculated 166). In fact, the approximation works well only for the elastic moduli, it is satisfactory for strength properties, but deformation...

Other elements of glass structures must be included in order to discuss more subtle variations in properties and various spectra. The field strength of both network-forming and network-modifying cations must be included in discussions of trends in properties with glass compositional variations. Since many modern studies include variations in the identity of the anions which link the structure, their field strengths and ionic radii are also important. The atomic radii of mobile cations, anions, and atoms and molecules must be considered in structural models seeking to explain transport properties. 

In the last decade, major technological developments have occurred in the production of polymer fibers with high mechanical strength and stiffness. In concert with these efforts, studies have been directed toward a better understanding of the relationship among chemical composition, physical structure and mechanical properties. One goal is to develop predictive structure-property models to develop marketable technologies. The discussion that follows includes examples of the types of nucroscopy... 

Recently, Yu et al. [6] provided a comprehensive review of existing computational models to analyze trends in mechanical properties, e.g., yield Stress CTc or tensile strength. The following analytical expression for the modified rule of mixture model is most coimnonly used to relate stress values to contemporary concepts of glass fiber structure and polymer property relationships ...
