This article proposes a heuristic model to predict the fatigue life of rubber parts. The developed model is mainly based on the Cracking Energy Density (CED), originally developed by Mars, for the study of rubber parts fatigue. The main contribution consists in the integration of the theoretical framework of the critical plane analysis proposed by Mars with Saintier's experimental research carried out in tension and torsion modes. The CED parameter, derived from the Strain Energy Density (SED), can predict the occurrence of the first crack and its possible orientation depending on the type of loading path. In this context, an analytical analysis of this parameter is carried out for typical loading cases. Furthermore, the variation of CED by SED ratio (WC/W), as a function of the probable crack angle θ and the principal stretch λ1 is investigated. A finite element (FE) model is, then, developed to measure the performance and efficiency for some basic criteria used to investigate rubber fatigue life in literature. The pertinence of such criteria is evaluated in terms of a determination coefficient. The CED parameter can be considered as the most effective criterion for describing the multiaxial fatigue life of rubbers.

“…In recent years, researchers have tried to develop advanced finite element models for the micro-scale analysis of short fiber reinforced rubber composites. [12][13][14][15][16][17][18] The computed stress and strain fields were then used with a homogenization technique to predict the macroscopic response of the composites. For example, Zhang et al 12 prepared composites based on nitrile butadiene rubber (NBR), sepiolite fiber, and resorcinol-formaldehyde latex-coated aramid short fibers.…”

Effects of nonlinear hyper‐viscoelasticity and matrix/fiber debonding on the mechanical properties of short carbon fiber/styrene‐butadiene rubber composites under cyclic uniaxial loading using a multiscale finite element model

A multiscale finite element analysis was performed for short carbon fiber (SCF) reinforced rubber composites under uniaxial tensile loading with periodic geometries and random distributions of the short fibers. Three different zones were considered, including the rubber matrix, SCF as the inclusion phase, and a thin matrix layer as the interphase. A nonlinear hyper‐viscoelastic model was selected for the matrix, while linear viscoelastic and elastic models were considered for the interphase and reinforcing phases, respectively. The analyses were carried out on an incremental basis from a lower loading‐unloading rate of 10 mm/min to a higher rate of 100 mm/min. Two interface conditions were considered between the polymer matrix and the SCF phases: perfect bonding and partial debonding. The partial debonding was modeled via extended FEM (XFEM) with a crack initiation criterion. An integral averaging technique was employed to predict stress and strain at the macro‐scale. Based on the observations in this work, hysteresis and energy dissipation decrease with the addition of the short fibers to the neat rubber and surface modification of the fibers under three‐cycle loading. For example, in the first cycle and for a constant stress of 0.45 MPa, the strain value decreases from 0.25 to 0.17 MPa at the loading‐unloading rate of 10 mm/min. The high‐fidelity model developed in this work for short fiber/rubber composites is able to predict the stress and strain responses of the SCF/SBR composites, confirming the accuracy of the utilized multiscale approach.

“…27 In order to improve the accuracy of such fatigue predictions, the probabilistic methodology, 28 the artificial intelligence method, 29 and the finite element approach for interfacial fatigue damage in rubber composites have also been studied. 30,31 Two approaches to dealing with rubber fatigue cracks caused by mechanical failure emerge from the above review: continuum mechanics (total life) and fracture mechanics (defect tolerant). The principal difference between these may depend on how the crack initiation (nucleation) and crack propagation stages of fatigue are quantitatively defined.…”

In antivibration applications, it is essential that the given rubber product has a suitable service period; therefore, an accurate fatigue assessment during design is key. In this study, the effective stress approach was applied to two industrial products: a drum mount for road engineering and a Metacone spring for rail vehicles. This method employed a three-dimensional tensor that took all principal stress ranges into consideration, without underestimating fatigue damage, in a multi-axial stress state. As both the magnitude and direction of the effective stress were obtained based on analytical functions, there was no need to use the expensive critical plane search method to detect the plane of failure. The calculated angles (67.5° and −63.2° from the horizontal plane, respectively) were validated against the observed fatigue cracks. Engineers would be able to accelerate their design processes by using the approach presented in the current study, due mainly to three aspects: visualising all of the whole product's hot spots, circumventing an expensive critical plane search, and presenting the effective stress ranges. As the proposed effective stress approach was validated in only two specific industrial cases, an investigation into further engineering applications is still needed to lend this concept greater support.
