Mechanics of thin-walled curved beams made of composite materials, allowing for shear deformability

Linear viscoelastic analysis of straight and curved thin-walled laminated composite beams

“…In Fig. 4 one can see a comparison between the curved beam model (Piovan and Cortínez, 2007b) and a computational finite element approach performed with shell elements of the Commercial Program Cosmos/M. The shell models were prepared with more than 3000 SHELL8T finite elements whereas the response of the one-dimensional model was performed with four curved finite elements.…”

“…In these cases differences of less than 2.5% have been reached between the shell and beam approaches. In a recent work of the authors (Piovan and Cortínez, 2007b) one can find extensive comparisons of the thin-walled curved beam model for composite materials, in different linear elastic problems (static, vibration and buckling).…”

Non-linear dynamic response to simple harmonic excitation of a thin-walled beam with a breathing crack

“…Thin-walled beams have not been addressed in depth, perhaps due to their more complex dynamics, usually presenting a strongly coupled vibrational response [14][15][16][17][18][19][20][21][22].…”

Generalized Warping Effect in the Dynamic Analysis of Beams of Arbitrary Cross Section

“…Some researchers have employed the assumptions of TTT (Thin Tube Theory) and the nonuniform torsion theory with an additional degree of freedom for nonuniform warping that is the rate of angle of twist [23][24][25][26][27][28][29][30][31][32][33][34] or an independent warping parameter [35][36]. Egidio et al [37] describe the non-linear warping of open crosssection thin-walled beams in terms of the flexural and torsional curvatures.…”
