“…As an example, a comparison of the Young's modulus of Al/SiC composite predicted by the ROM with the experimental results of Bhattacharyya et al (2007) is presented in Table 1, which shows an error of 38% in the ROM for a ceramic volume fraction of 40%. Still, many studies continue to use the ROM for modeling FGM structures (Reddy, 2000;Woo and Meguid, 2001;Sofiyev, 2003;Croce and Venini, 2004;Patel et al, 2005;Abrate, 2006;Zenkour, 2006;Pradyumna and Bandyopadhyay, 2008;Han et al, 2009;Tornabene et al, 2009;Akbarzadeh et al, 2011;Hamidi et al, 2012;Viola et al, 2012;Qu et al, 2013;Ebrahimi and Najafizadeh, 2013;Thai and Choi, 2013;Thai and Kim, 2013).…”
