“…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.

“…Looking at the most-known compositions as ceramics and metal, ceramics are usually responsible for resistance to high temperatures, but metal can endure most plastic deformations. In regards to the literature, for over thirty years many works were devoted to the theoretical analysis of the behavior of FGM structures under thermal and/or mechanical loads [5][6][7][8][9][10][11][12][13][14][15][16][17]. One of the first works devoted to a study on FGM structures was elaborated by Praveen and Reddy [18], who analyzed the behavior of the plate under static and dynamic loads.…”

This work deals with the investigation of the strength and the stiffness of samples built of step-variable functionally graded material (FGM). The considered FGM samples consist of two main components: WC and NiCr with some content of Co as a conjunction of structure. The samples were fabricated on the basis of the detonation gun layer deposition method which is regarded as a novelty in the case of FGM production. The analyzed samples possess a finite number of layers with different varying fractions of each constituent across the wall. The basic tests of bending were conducted to assess the influence of used components in adequate proportions on the stiffness and the total strength in bending. In addition, to validate the numerical approach, simulations of samples under similar loads with truly reflected material distributions were carried out. The material properties of components were determined due to micro-nano-hardness by instrumental indentation techniques. The numerical calculations were performed with the use of the material characteristics for each material and with a consideration of large deflections. Furthermore, by means of an electron microscope, the composition of materials and distribution of chemical elements across the thickness of samples were examined. This paper reveals the experimental results of FGM samples manufactured by detonation gun layer deposition which allows the creation of layer by layer moderately thin-walled structures. It was shown that the indentation method of a determination of Young's modulus gave higher values in comparison to values attained in the bending test. Moreover, it was stated that a modelling of FGM still requires the study of each layer separately to clearly predict the strength of the whole FGM structure.

“…Many researchers in past have worked upon to understand behavior of functionally graded plates. Reddy [1] carried out nonliear finite element static and dynamic analyses of functionally graded plates using Navier's solution, Vel and Batra [2] presented threedimendional exact solutions for free and forced vibrations of simply supported functionally graded rectangular plates, Tinh Quoc Bui et al [3] used finite element method to study static bending and vibration of heated FG plates. Dao Huy Bich et al [4,5], Nguyen Dinh Duc et al [6,7] used analytical method to study vibration, nonlinear respones of eccentrically stiffened functionally graded cylindrical panels [4,5] and nonlinear postbucking of FGM plate and eccentrically stiffened thin FGM resting on elastic foundations in thermal environments [6,7].…”

Free vibration of functionally graded sandwich plates with stiffeners based on the third-order shear deformation theory

2016

View full text Add to dashboard Cite

Abstract. In this paper, the free vibration of functionally sandwich grades plates with stiffeners is investigated by using the finite element method. The material properties are assumed to be graded in the thickness direction by a power-law distribution. Based on the third-order shear deformation theory, the governing equations of motion are derived from the Hamilton's principle. A parametric study is carried out to highlight the effect of material distribution, stiffener parameters on the free vibration characteristics of the plates.
