“…However, the research on the mechanical properties of the metallic foams has been focused prominently on uni-axial compressive loading. There are few studies investigating the cyclic loading of metallic foams in compression-compression [2][3][4][5][6][7][8][9], tension-tension [10][11][12][13], or tension-compression [1,[14][15][16] conditions. Some research compared the response of the foams in different loading conditions [17][18][19].…”

Abstract:The main purpose of this paper is to present the basic fatigue properties of metal matrix syntactic foams (P-MSFs). The investigated syntactic foams consisting of expanded perlite and A356 aluminum matrix were produced using an inert gas pressure infiltration technique. The obtained foams were subjected to cyclic compressive loading in order to investigate their fatigue properties. The standard procedure for cyclic fatigue testing was slightly modified to account for the variation of porosity and strength which is typical for metallic foam samples. This approach allows the direct comparison of the fatigue test results between all investigated samples. Depending on the applied load level, two different failure mechanisms were identified that resulted in characteristic deformation -loading cycle curves. The failure mechanisms were further investigated on the microstructural scale: traces of fatigue beachmarks and extensive plastic deformation were found. Furthermore, Wöhler-like deformation -lifetime diagrams were created in order to predict the expected lifetime of the P-MSFs.http://mc.manuscriptcentral.com/jcm AbstractThe main purpose of this paper is to present the basic fatigue properties of metal matrix syntactic foams (P-MSFs).

“…Fatigue behaviour of various aluminium alloys and their different chemical compositions have been studied extensively. Studies mainly focused on the different fatigue behaviour of different aluminium alloys, while few of them focused on specimens under low cycle fatigue and high cycle fatigue . Numerous studies regarding the fatigue life of various aluminium alloys under different temperatures have been conducted.…”

In the present study, the results of the monotonic tension tests and low cycle fatigue tests performed on aluminium alloy EN AW‐2024‐T3 under various operating temperatures are presented in order to assess the fatigue behaviour of the aluminium alloy under evaluated temperatures. Monotonic tests were performed to determine the influence of temperature on mechanical properties of the material. The aim of cyclic tests was to acquire the parameters required for Manson–Coffin equation in order to plot strain–fatigue life curves. Moreover, stress–strain behaviour of the alloy and the cyclic hardening behaviour were evaluated using Ramberg–Osgood equation. Finally, PSWT‐damage parameters for each temperature have been calculated for further investigation of the effects of the temperature on fatigue life using acquired data while taking the account of mean stress effect into calculations. Variations in the experimental data due to various test temperatures are presented for both monotonic and cyclic tests.

“…[1][2][3][4][5] A replication process typically involves the three main steps of: preparing a porous preform, filling the pores with foam material, and removing space-holders (usually by dissolution). [2,6,7] Independent control of pore size, pore shape, and relative density, [1,2,4,6,[8][9][10][11][12] possibility of producing foams with pores of a few microns in size, [9,10,[13][14][15][16][17] opportunity of creating nearly fault free and uniform structures critical for repeatable mechanical tests, [6,8,10,[16][17][18] being applicable to various metals and alloys, [2,5,14,17,19] and simplicity of producing functionally graded structures, [20,21] are some of the benefits, which make replication a unique technique in the field of cellular solids.…”

This paper proposes a numerical framework for realistic simulation of replicated foams. The method is inspired by the actual processes used in the manufacturing of this class of cellular materials. Accordingly, an assembly of space-holders is generated first, then the physical process of cold isostatic pressing is simulated and, finally, the structure resulting from the leaching process is modeled using a voxel-like finite element model and an efficient inverting algorithm. A simple yet effective solution for the simulation of the influence of infiltration pressure on the microstructure of foam is also suggested. Next, the numerical approach is verified using the experimental results of a set of replicated aluminum foams whose preforms were monomodal spherical salt grains. Samples with various relative densities are modeled and their elastic and yield properties are compared to those of tested samples from the literature. Satisfactory agreement has been achieved, which confirms the usefulness of the proposed approach.
