Network resistant

In reality, the radiation shape factors F, 2, F( m, and F2 m are unity for this example, so that the expression for the heat flow could be simplified to some extent however, these shape factors are included in the network resistances for the sake of generality in the analysis. 

TBP corrrpletely ruptures hard block domains of rrrethane urea re rdless of their initial concerrtration of elastomer. Orrly SPU chemical network resists swelling by TBP. The eqrrilibrirrm swelling of SPU in DBP decreases with increase in concerrtration of hard blocks. As a result tensile strength of a material is decreased to a lesser degree. The lowest decrease in terrsile strength is observed in SPU-1 swollen to equilibrium in DBP. SPU-1 has 37% hard blocks (Figirre 10.80). 

Given the complexity of these highly distributed and interconnected infrastructures, performing a systematic analysis of their vulnerabiHty and robustness to failure becomes difficult if one resorts only to traditional probabilistic safety assessment (PSA) methods, so that new complementary approaches of network analysis are emerging for characterizing the network resistance to failure and identifying its most vulnerable elements (Hines (2008), Newmann (2003), Freeman (1978,1979), Koonce (2007), Cadini (2008), Zio (2008).
