“…However, a large number of parameters influence the durability of rubber materials [15][16][17][18][19][20][21][22]. Thus, in order to design and manufacture reliable parts, the effective prediction of fatigue life still needs to be better understood and modelled.…”

A New Multiparameter Model for Multiaxial Fatigue Life Prediction of Rubber Materials

et al. 2020

Most of the mechanical components manufactured in rubber materials experience fluctuating loads, which cause material fatigue, significantly reducing their life. Different models have been used to approach this problem. However, most of them just provide life prediction only valid for each of the specific studied material and type of specimen used for the experimental testing. This work focuses on the development of a new generalized model of multiaxial fatigue for rubber materials, introducing a multiparameter variable to improve fatigue life prediction by considering simultaneously relevant information concerning stresses, strains, and strain energies. The model is verified through its correlation with several published fatigue tests for different rubber materials. The proposed model has been compared with more than 20 different parameters used in the specialized literature, calculating the value of the R2 coefficient by comparing the predicted values of every model, with the experimental ones. The obtained results show a significant improvement in the fatigue life prediction. The proposed model does not aim to be a universal and definitive approach for elastomer fatigue, but it provides a reliable general tool that can be used for processing data obtained from experimental tests carried out under different conditions.

“…Some researchers [11][12][13][14][15] have studied the fatigue behavior of rubber materials under cyclic tension loading conditions. Up to now, only several studies study the fatigue behaviors of SBR under compression loading conditions with different crosslink network structures [16][17][18].…”

“…Le Cam et al [19] described fatigue behavior in natural rubber filled with carbon black under tension-compression conditions. Seichter et al [14] studied the effect of frequency on the fatigue behavior of SBR/NR/BR blends under uniaxial loading. Wu [20] studied the compression fatigue behavior of compound concrete and discussed the changes in the dissipated energy, Poisson's ratio, residual strain, and fatigue modulus of the cylindrical samples with the number of compressive cycles.…”

e effect of network structure on dynamic compressive fatigue behavior and static compressive mechanical properties of styrenebutadiene rubber (SBR) were investigated. A series of SBR compounds with different amounts of sulfur and dicumyl peroxide (DCP) were prepared, and their crosslinking densities were calculated using the Flory-Rehner equation. Compressive fatigue resistance and creep behavior of the vulcanizates were performed on a mechanical testing and simulation (MTS) machine. e fatigue damage surface of SBR vulcanizates before and after a dynamic compressive fatigue test was observed with a scanning electron microscopy (SEM). e results suggested that the surface of the samples was badly damaged as the number of compressive cycles increased. By comparison, compressive fatigue caused less surface damage to sulfur-cured SBR than to peroxide-cured SBR. e peroxide-cured SBR samples showed higher energy dissipation than sulfur-cured SBR during cyclic compression. e peroxide-cured SBR showed lower creep strain and compression set than the sulfur-cured SBR. e -Sxlinkages provided by the sulfur curing system allow dynamic compressive deformation but suffer from poor static compressive resistance. However, the carbon-carbon linkages from DCP are irreversible and provide higher resistance to static compressive stress, but they do not show obvious dynamic compressive fatigue resistance.

“…The researchers first studied the fatigue life of rubber materials under displacement control 3,4 . Duan et al 5–7 conducted a large number of experiments on the effects of the strain ratio R , variable amplitude load, maximum strain, and high and low frequencies on the rubber fatigue life. Abraham 8 tested the uniaxial fatigue behaviour of ethylene propylene diene rubber (EPDM) and styrene butadiene rubber (SBR) and found that the fatigue life decreased with increasing stress amplitude and increased with increasing minimum stress while the alternating stress remained constant.…”

Two natural rubber (NR) compounds of hardness shore A 60 and 70 with 10 different biaxial displacement/twist paths were investigated using an axisymmetric cylindrical hollow dumbbell specimen. The effects of the proportional and non‐proportional loading modes on the fatigue life are discussed. In total, 52 fatigue test results are reported with fatigue life results of 3,918 to 488,000 cycles. The effect of the channel phase on the fatigue life is discussed.
