A B S T R A C T A known factor that limits the performance of automotive front-end accessory serpentine belt drive is cracking of the elastomer located in the rib tip. In this paper, fracture experiments were conducted using single-edge notched tension (SENT) specimens to study the fracture behaviour of a belt rib compound. A finite-element modelling method utilizing singular elements for crack in rubber solid was proposed and implemented in both planestress and 3D solid models using ABAQUS. A newly developed neural-network-based model was used to represent a nonlinear elastic belt rib rubber compound. The crack finite-element model, along with the neural-network-based material model, was verified with analytical and experimental results. A global-local finite-element procedure was developed to evaluate the J-integral for mode-I through-the-thickness crack in V-ribbed belt rib. Effects of pre-crack length, pulley pre-load and backside pulley displacement were investigated.

“…For the deformation plasticity theory, McClintock (21) has demonstrated, through the crack tip plastic stress and strain equation expressed from the HRR singularity, the existence of a singularity in r whose strength is the J-integral. Because of the apparent popularity of the J-integral as an elasticplastic fracture criterion, the validity of extending the application of the criterion to carbon black reinforced rubber vulcanizates has been examined and proved to be satisfactory (22)(23)(24).…”

The recent emphasis on improving tyre structure integrity against premature failures has led to an increased effort to study fracture behaviour of different carbon black reinforced tyre compounds. Due to the general hysteretic nature of tyre materials, the overall working temperature of a tyre is elevated under service conditions. Relative merits in the characterization of crack initiation in a typical tyre compound using the conventional quasi-static energy and .I-integral approaches were first examined. The quasi-static energy method has been applied to evaluate the fracture toughness of materials exhibiting either linear or non-linear elastic behaviour within the confines of the linear elastic energetic approach. Based on the ease of analysis and ability to make multiple measurements on a single specimen, the quasi-static energy approach is chosen to measure the fracture toughness of the tyre material at temperatures of 23,37,52,62 and 73°C. The fracture toughness measured for the tyre material has been observed to be inversely proportional to the temperature elevation. The observation agrees with earlier investigations that the crack growth rate of rubbers under fatigue loading decreased with an increase in temperature in the test materials.C03488 Downloaded from 25 Chow, C.

ARTICLE This journal isExfoliated graphene oxide (GO) reinforced natural rubber (NR) composites were prepared by a simple and promising latex co-coagulation method. Latex co-coagulation realized the complete exfoliation and uniform dispersion of GO in NR matrix. The quasi-static fracture and dynamic fatigue behaviors of composites were investigated. Mechanical properties and J-testing were used to characterize the fracture resistance, and fatigue tests were carried out under cyclic condition of constant strains. Results revealed that with increase in GO sheet content, the mechanical properties, fracture initiation and propagation resistance were all highly improved. A much higher reinforcing efficiency of GO sheets than that of traditional fillers was realized. Fatigue crack growth resistance was remarkably enhanced with the incorporation of only 1 phr GO sheets. The relatively weak fatigue resistance of composites filled with 3 phr and 5 phr GO was attributed to their high hysteresis loss and tearing energy input. It revealed that GO sheets would be promising filler in preparation of rubber composites with high fracture and fatigue resistance at low filler content.
