Analysis of thin-walled open-section beams with functionally graded materials

The Buckling and Post-Buckling of Steel C-Columns in Elevated Temperature

“…Studies on the stability of structures under mechanical loads were widely included in papers [14][15][16][17][18][19], among others. Based on allowable literature, only a few papers concerning an experimental study of the stability of thin-walled structure under elevated temperature can be found.…”

“…Likely, the authors in paper [9] examined the bending of beams made of high-strength steel in temperatures of up to 1000 • C. On the other hand, taking into consideration of analyses of elements subjected to a temperature field in theoretical aspects, one can find many papers devoted to the thermal buckling and the thermal post-buckling of thin-walled structures made of functionally graded material in references [10][11][12][13]. Studies on the stability of structures under mechanical loads were widely included in papers [14][15][16][17][18][19], among others.…”

Nonlinear buckling behaviours of thin-walled functionally graded open section beams

“…3) Type C: the bottom is graded from fully metal to fully ceramic the while the top skin is entirely ceramic [22]. Vc can be determinated as:…”

“…[22,32], the center of gravity (x0, y0) is described as the axial force application point, the acting point of axial stresses resultant caused by a constant state of strains 0 z  . From moments equality with respect to the x and y axes: 00 ,…”

“…Although many researchers investigated vibration or buckling analysis of FG beams with rectangular cross-section [13][14][15][16][17][18][19][20], thin-walled box section [21] and open section [22,23], according to the authors' knowledge, there is no work available to study flexural-torsional and lateral buckling of FG open section beams in a unitary manner. As a result, this is also main objective of this paper.…”
