“…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].…”

“…Sua et al in reference [8] studied the behavior of aluminum alloy beams at elevated temperatures ranging from 24 • C to 600 • C. They validated the experiment employing the finite element method. 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.…”

This work deals with the investigation of a steel thin-walled C-column subjected to compression due to temperature increase. These experimental studies of the compressed columns in post-buckling state were conducted to determine their load-carrying capacity. To ensure appropriate supports and keeping of columns, plates with grooves were constructed. The tests of the columns' compression for different preloads were carried out. By comparing the experiment results, numerical calculations based on the finite element method (FEM) and the semi-analytical method (SAM) of solution were performed. The computations were executed with the use of full material characteristics with consideration of large strains and deflections. Furthermore, while observing the deformation of columns, a non-contact Digital Correlation ARAMIS ® system was employed whose calculated results of deformations are very close to the results of the numerical method. The paper revealed that maximum recorded loads under temperature rise are comparable regardless of a value of initial load. A good correlation in results between used methods was achieved. The main goal of the present work was to assess of behavior of thin-walled compressed steel columns in a temperature-controlled environment till their full damage.

“…Arefi et al [4] analyzed the static behavior of a FG-CNTRC cylindrical pressure vessels subjected to pressure and thermal loadings by using the FSDT theory. Recently, Trabelsi et al [63,64] investigated the thermal buckling and post-buckling of FG plates and shells using a modified FSDT theory. As can be remarked from this report of the open literature, most of the papers used the FSDT or HSDT theories to predict thermal buckling and post-buckling behavior of FGM structures.…”

In this paper, we extend the Kirchhoff-Love model to thermal buckling and post-buckling analysis of functionally graded structures. The kernel idea of the proposed model consists of the consideration of large displacements and finite rotation to accurately model the thermal effects on buckling and post-buckling behavior of such structures. Both uniform and nonuniform temperature distributions are considered. Material properties of the FG structures are graded in the thickness direction and assumed to obey a power law distribution of the volume fraction of the constituents. The effectiveness and usefulness of the proposed model are highlighted through different numerical examples, and the effects of the volume fraction exponent, thermal loads, length-to-thickness ratio, boundary conditions and geometrical parameters on the buckling and post-buckling behavior of FGM structures are also examined.

“…In works [11,12], constitutive relations referred to neutral physical surface for functionally graded materials based on nonlinear six-parameter shell theory. A response of FGM shell structures under thermal load within the first-order shear deformation theory (FSDT) was investigated in reference [13]. The behaviour of the FGM plate subjected to in-plane compressive or thermal load and combination of both loads, on the basis of the classic plate theory (CPT), was studied in [14].…”

The analysis of gradations through the thickness in structures are commonly used. It usually refers to the problems of the stability of functionally graded (FG) structures. In this work, rectangular in-plane FG plates built of a material gradation along the transversal direction were assumed. Five-strip FG plates with four cases that were based on the boundary conditions on longitudinal edges and simply supported on transverse loaded edges were considered. The non-linear stability problems of the FG plates that were subjected to linear approaches of the transverse edges for several types of loads were solved. The estimations were executed with two methods: an analytical-numerical way based on Koiter’s theory and finite element method (FEM).
