Comments on "A Rankine-Timonshenko-Vlasov beam theory for anisotropic beams via an asymptotic strain energy transformation"

초록

In their paper (Kim and Kim, 2013), Kim and Kim presented predictions that exhibited significant differences in bending-shear coupling for the CUS box beam from their own analysis vis-a-vis from VABS (Yu et al., 2002, 2012). The actual differences between results obtained from VABS (Yu et al., 2002, 2012) and the RTV theory (Kim and Kim, 2013), when executed properly, are shown herein to be very minor. Indeed, both stiffness models yield very acceptable results for a static analysis. Specifically, VABS does not significantly deviate, qualitatively or quantitatively, from 3D FEM predictions, in contrast to results presented in Kim and Kim (2013). Published by Elsevier Masson SAS.
