J-Integral Analysis of Cord-Rubber Serpentine Belt Using Neural-Network-Based Material Modeling

Abstract

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 plane-stress 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.
