This paper investigates the lifetime reinforcement at different temperatures of carbon black filled natural rubber under non-relaxing torsion. Torsion fatigue tests with angle ratios have been carried out axisymmetric-shaped specimens. Finite element analysis was used to predict local mechanical state by taking into account temperature effects and stress softening heterogeneities. It has shown that when test is increased, response does no longer stabilize, contrary what observed ambient...
ABSTRACT In this paper, the fatigue life prediction of a carbon black filled natural rubber was carried out using an artificial neural network. A wide range loading ratios were considered under relaxing and non‐relaxing conditions in order to fully describe response, especially lifetime reinforcement. As reinforcement is generally assumed be due highly thermosensitive phenomenon, namely, strain‐induced crystallisation, tests performed at three different temperatures. The criterion defined...
Abstract In this paper, the effect of non‐relaxing torsion loadings on fatigue lifetime reinforcement carbon black filled natural rubber is fully addressed. Torsion tests with different loading ratios have been performed highly notched axisymmetric‐shaped specimens. Finite element analysis used to predict mechanical state at any point in The prediction significantly improved by taking into account heterogeneous accommodation. first Haigh diagram under built and analyzed calculating minimum...
The present study investigates the effect of active chain density and cross-link length on Mullins softening in natural rubber by using a wide range vulcanization systems (conventional, semiefficient, efficient). For that purpose, sulfur [S] accelerator [A] contents, as well their ratio [A]/[S], have been varied. Different conditions, corresponding to various times temperatures, also tested. In order investigate how fillers affect relationship between network softening, tests were conducted...
