“…Lately, energetic criteria have been investigated coupling several techniques (Le Saux et al 2010 [1], Ayoub et al 2012 [2]) or focusing on the study of a single parameter (Mars 2001 [3], 2002 [4] with, for example, Cracking Energy Density). Lacroix 2004 [5] and then Poisson et al 2011 [6] have been working with the hysteresis energy and their crack initiation approach provided good results regarding fatigue life predictions of a polychloroprene rubber. These authors [6] developed a Haigh diagram for a polychloroprene rubber ( fig 1) and observed that below a force ratio of R=0.2, fatigue lives decrease with increase of R-ratio, whereas above this threshold value, the fatigue lives increase clearly: fatigue lives at R=0.5 are more than 10 times greater than those at R=0.2.…”

The suggested mechanism is possible strain-induced crystallization of the polychloroprene rubber that influences the fatigue life above R=0.2 [7].…”

3rd International Conference on Material and Component Performance under Variable Amplitude Loading, \VAL\ 2015International audienceAbstract In this study we study the fatigue behavior of a polychloroprene rubber using designed specific variable amplitude tests to gather insight into such material behavior. Firstly, increasing force amplitude block load tests were carried out that permits us to determine the stress amplitude at which fatigue damage is significant. In a second series of tests block programmed tests were carried out. During these tests the hysteresis energy and stiffness were also measured. These measurements bring out possibly a competition between two mechanisms the crystallization effect and the effect of crack propagation. The first mechanism tends to increase the stiffness while the second decreases the stiffness

“…In the opinion of References [24][25][26], this criterion is better than those previously mentioned whether for uniaxial or multiaxial solicitations. [27] This damage parameter was used to study the fatigue behavior of polychloroprene rubber. [28] As the DED is a scalar parameter, it cannot provide any indication of the crack direction.…”

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.

“…The fenders used in commercial docks, ports, and harbors are mostly fabricated from rubber because of its outstanding performances, like low transmission force and excellent energy absorption capacity. In addition, rubber has many more favorable properties such as high flexibility, good resilience, a long service life [1][2][3][4][5][6], an excellent resistance toward temperature [6][7][8][9][10][11][12], saltwater [13,14], and other environmental factors [15][16][17][18][19].…”

Effect of Wall Thickness on Stress–Strain Response and Buckling Behavior of Hollow-Cylinder Rubber Fenders

et al. 2020

In this study, the effect of wall thickness (15–25 mm) on the stress–strain response of hollow-cylinder rubber fenders were investigated by conducting monotonic compression tests. It was found that a progressive increase in lateral bending deformation was observed during monotonic compression. Simultaneously, the extent of the lateral deflection decreased notably with an increasing wall thickness. From the experimental results, the fact is accepted that buckling occurred in the tested fender due to the fact that the ratio of the height to the wall thickness was higher than four in all of the considered cases. Moreover, an s-shape profile appeared in the stress–strain curves, which became clearer as the wall thickness was reduced from 25 to 15 mm. To assess the performance of fenders objectively, an energy-effectiveness index, C E R , was introduced to quantify the energy absorption capacity of the fender. From the experimental observations, it was inferred that the contact area of the folded inner surface of the fender produced under compression generated an additional reaction force and affected the shape of the stress–strain curve since the measured load consisted of two reaction forces: one caused by the self-contact area, and the other resulted from the compression-bending deformation that occurred in the side wall of the fender. To examine this assertion, a finite element analysis (FEA) was conducted and confirmed the effect of the reaction force on the sensitivity of the s-shape characteristic of the stress–strain curve. Finally, a polynomial regression was conducted and the calculated results based on the fourth-degree stress polynomial function correlated very well with the measured stress–strain curves.
