Rubber industry in Indonesia needs a deep research study about characteristic and properties of rubber so it can produce the better quality of rubber’s derivative product. Such research can be used in industry to predict rubber fatigue life when applied to unique loading condition. One of the researches is to conduct comparison analysis of constitutive hyperelastic model. <br /> <br /> <br /> This research proposes a thorough comparison of Ogden, Tube, and Haines – Wilson model to obtain the best model in describing the stress – strain behavior of rubber-like material. The ability of each model to reproduce different types of loading conditions is analyzed thanks to experimental data of PT CDM rubber from previously done research and literature data of Jörgen Bergström. <br /> <br /> <br /> on those data sets, the material parameters of each model are determined by curve fitting procedure to be then reproducing the stress strain curve of every type <br /> <br /> <br /> of rubber. Those models are then compared and ranked using the error value they produce as indicator. <br /> <br /> <br /> In the case of PT. CDM rubber, Haines – Wilson model gives the best result among the other in describing stress – strain occurred. As in the case of Jörgen Bergström literature data, Haines – Wilson is still positioned at first.
