The book covers the fatigue testing of specimens, curve fitting of equations to the test data, and the use of such equations in life prediction. Earlier chapters are background in the nature of rubber, history of its usage, brief mention of types of rubber and manufacturing methods. Stress-strain testing and behavior will be covered to the extent relevant to fatigue analysis. Also the text will cover the application of finite element analysis to components to determine high stress points which are vulnerable to fatigue failure.

Due to their unique properties, rubber materials are found in multiple engineering applications such as tires, engine mounts, shock absorbers, flexible joints, seals, etc. Nevertheless, the complex nature of the behavior of such material makes it difficult to accurately model and predict the performance of these units. The challenge to correctly reproduce the observed characteristics of rubber elements necessitates detailed experimental investigations, development of accurate constitutive models, validation of techniques to identify material parameters and efficient numerical methods. Aspects regarding fatigue and damage in elastomers are not to be left aside, as they influence the durability of the products. State-of-the-art technology in terms of constitutive modeling, numerical implementation, damage and fatigue resistance are strongly represented in these Proceedings, along with insights into advanced elastomers to be used in novel applications. Topics included in this volume are: Ageing, Friction and abrasion, Adhesion, Swelling, Continuum mechanical models and numerical implementation, Hyperelasticity, Micro-mechanical approaches, Fracture and fatigue, Mullins effect, Strain induced crystallization, Thermal effects, Reinforcement and vulcanization, Design and applications, Smart elastomers. Constitutive Models for Rubber VIII is of interest not only for undergraduates, postgraduates, academics and researchers in the discipline, but also for all those design and development engineers in the industry.

This book provides the beginning engineer with the principles of rubber science and technology: what rubber is, how it behaves, and how to design engineering components with rubber. It introduces the reader to the principles on which successful use of rubber depends and offers solutions to the questions engineers in rubber processing face every day: - How is an elastomer chosen and a formulation developed - Why is rubber highly-elastic and relatively strong - How to estimate the stiffness and the strength of a product - How to guarantee high quality and durability The authors describe current practices in rubber engineering. At the end of each chapter, sample questions and problems (together with solutions) are provided, allowing the reader to gauge how well he/she has mastered the material. Contents: - Materials and Compounds - Elasticity - Dynamic Mechanical Properties - Strength - Mechanical Fatigue - Durability - Design of Components - Finite Element Analysis - Test and Specifications.

In this study, a styrene butadiene rubber, which is similar to the rubber used in road wheel backer pads of tracked vehicles, was investigated experimentally under monotonic and fatigue loading conditions. The monotonic loading response of the material was obtained under different stress states (compression and tension), strain rates (0.001/s to 3000/s), and temperatures ( -5C to 50C). The experimental data showed that the material exhibited stress state, strain rate and temperature dependence. Fatigue loading behavior of the rubber was determined using a strain-life approach for R=0.5 loading conditions with varying strain amplitudes (25 to 43.75 percent) at a frequency of 2 Hz. Microstructural analysis of specimen fracture surfaces was performed using scanning electron microscopy and energy dispersive x-ray spectroscopy to determine the failure mechanisms of the material. The primary failure mechanisms for both loading conditions were found to be the debonding of particles on the order of 50 to 200 m.

In the new millennium era, rubber materials are vigorously used in many industries including automotive that cover a wide range of applications such as tires, seals, belts, bushes and engine mounts. Rubber is an ideal material for many applications because it can withstand very large strain with no permanent deformation or fracture. The behavior of material under repeated loads differs from static loads. Elastomers fail at cyclic stress or strain amplitude much lower than static stress or strain. It is based on growth of cracks through the material. The fatigue analysis and its lifetime evaluation are very important in design procedure to assure the safety and reliability of the rubber components. Design of rubber against fatigue failure is one of the important topics to be focussed for checking the failures during its operation life. Many mechanical and environmental factors could prolong the rubber fatigue life. The fatigue failure process of materials is explained by two approaches including crack initiation and crack propagation. The present work deals with investigation of the fatigue behavior using rubber dumbbell test specimens under uniaxial loading. The material used in this study is a vulcanized natural rubber with a typical engine mount formulation and the hardness of International Rubber Hardness Degree 60. Test specimens were designed based on type 2 of MS ISO 37 standard and used for tensile and fatigue tests, both in ambient temperature. Fatigue tests were conducted under the displacement controlled condition with a sine waveform of 0.1 Hz and the ratio of the minimum displacement to the maximum displacement was equal to zero. The experimental results were presented under strain controlled condition. For investigation of the fatigue damage behavior, a theoretical equation was developed based on the continuum damage mechanics theory. The Ogden strain energy potential of first order was used for defining a constitutive relation of the natural rubber. The proposed theoretical formula was based on function of the strain range under cyclic loading to determine the fatigue life of elastomeric material. The ability of predicted fatigue life shows a reasonable agreement of 98% with experimental values. The experimental results and theoretical equation were validated with the previous experimental data which show a good agreement of 97% and 93% respectively.

Hardbound. The First World Congress of Structural and Multidisciplinary Optimization (WCSMO-1) was held in Goslar, Lower Saxony, Germany from 28 May to 2 June 1995. Its aim was to bring together, at a single international meeting, researchers and practitoners in the field of structural optimization. This aim was met and these proceedings contain contributed papers presented at WCSMO-1, demonstrating the strong activity, recent advances and increasing importance of the field of optimum design. The book facilitates overview and easy access to these papers by categorizing them under 26 topics of modern optimization and by providing author and keyword indices.

In spite of the best efforts of technologists, rubber components fail in service from time to time. In some cases replacement of a particular item serves the purpose, but in others the failure may lead to serious consequences involving financial loss, environmental contamination or loss of life. The fractographer is required to establish the root causes in terms of design, choice, and quality of material, and to determine the mechanism of failure based on the nature/details or appearance of fracture surfaces. It is the purpose of the present book to treat under a single title the morphology of fracture surfaces obtained from tear, fatigue, abrasion and combinations of these. The book attempts to analyse fracture surfaces of simple rubber and rubber components and to correlate the failure/strength properties with the morphology of fracture surface. Although there is literature coming out from every corner of the world on fracture surface morphology, there is no single book devoted to this important class of material, namely rubber. Needless to say a similar attempt in the field of metallurgy has solved many intricate problems which are beyond the reach of simple mathematical analysis. The first six chapters deal with simple rubber and rubber-based com posites failed under controlled mode, namely, tensile, tear, fatigue, and abrasion. The remaining four chapters deal with the failure of rubber products and, hence, involve complicated analyses. As such, this book may serve as a guideline for further development of the subject in this field.
