Strain reduction

Work hardening is achieved by cold rolling. The yield strength increases with strain (reduction in thickness) according to... 

Theoretical and experimental studies on penta-coordinate silicon derivatives demonstrate that their existence is determined by a combination of factors electronegativity of the substituents and steric interactions between substituents. One should also emphasize the role and significance of polydentate ligand (chelate effect), the size and number of chelate rings involving the silicon atom, and strain reduction for five-membered ring system, wich can stabilize unusual structures, as well as to the role of medium effect. This is consistent with the results of NMR spectroscopic studies. 

What causes the phenomenon of stress and strain reduction and why is the reduction in impact and work properties so visible at small or negligible changes in elastic modulus and ultimate strengths As discussed previously, mechanical properties deal with stress and strain relationships that are simply functions of chemical bond strength. At the molecular level, strength is related to both covalent and hydrogen intrapolymer bonds. At the microscopic level, strength...

Table 1 gives a survey on the surface deteriorations in various scenarios. It is shown that the total number of the deterioration events is correlated to the strain reduction.

The FT model improves the predictions of the steady-state fiber orientation but has little effect on the strain at which the steady-state orientation occurs. In an attempt to control the rate of fiber reorientation, Sepehr et al., (2004) included a term to reduce the rate of fiber orientation termed the strain reduction factor or the slip coefficient. The slip coefficient, a, can be added to the FT model as follows,...
